Watch Movements Explained: What Powers Australian Watch Brands?
The movement is the engine inside a watch. It controls how the watch keeps time, how it is powered and, to a large extent, how much maintenance it will need over the years.
Terms such as quartz, automatic and manual-wind describe the type of movement. Names such as Miyota, Seiko/TMI, Sellita, Ronda and Soprod describe movement makers or calibre families.
That distinction matters when comparing watches.
Two automatic watches can feel similar on the wrist but use very different movements, with different power reserves, accuracy ranges and servicing considerations.
This guide looks at the main movement types found among brands in our round-up of Australian watch brands, including Luminius, Bausele, Melbourne Watch Company, Adina, Haigh & Hastings, BOLDR and Nicholas Hacko.
Battery Quartz Movements: Accuracy and Low Maintenance
A quartz movement uses a battery and a quartz crystal to regulate timekeeping. The big practical advantage is accuracy. Quartz watches generally need far less day-to-day attention than mechanical watches and have fewer moving parts.
That makes quartz a strong choice for an everyday watch that you want to pick up and wear without resetting regularly.
Luminius uses Japanese Miyota quartz movements across a number of its wood watches. Haigh & Hastings also uses Miyota quartz movements in models such as its AR24 chronograph and Profile range.
Adina uses repairable Swiss Ronda quartz movements in many of its watches.
Longevity
A good quartz movement can remain useful for many years when batteries, seals and worn components are replaced as required. Longevity also depends on whether replacement parts remain available.
Durability
Fewer moving parts can make quartz movements well suited to regular everyday use. The watch case, crown, seals and shock protection still play a major role in overall durability.
Accuracy
This is where quartz normally has the advantage over mechanical movements. It is the logical choice when keeping close time matters more than mechanical tradition.
Maintenance
Battery replacement is the main routine requirement, with seal checks particularly important in a water-resistant watch.
Adina's guide to watch movements gives a useful Australian watchmaker's explanation of why quartz movements are accurate and comparatively low maintenance.
Solar Quartz Movements: Quartz Convenience With Less Battery Handling
Solar quartz works on the same basic timekeeping principle as conventional quartz, but light is converted into electrical energy and stored in a rechargeable cell.
For the wearer, the appeal is straightforward: quartz accuracy with less need to open the case for routine battery changes.
Adina has introduced Swiss Ronda solar movements alongside its conventional battery-operated and mechanical ranges.
Longevity
Solar movements remove the regular disposable-battery cycle, although rechargeable cells and electronic components can still age over a long service life.
Durability
As with ordinary quartz, there are relatively few moving timekeeping components.
Case construction and water resistance remain just as important as the movement itself.
Accuracy
Solar power does not change the fundamental advantage of quartz regulation: dependable, low-fuss timekeeping.
Convenience
This is the key extra attribute. A watch that is regularly exposed to suitable light can be easier to keep running than either a battery quartz watch or a mechanical watch.
Japanese Automatic Workhorse Movements: Seiko/TMI NH Series
Automatic watches are mechanical watches that wind their mainspring through the movement of a rotor as the watch is worn.
They do not need a battery, but they contain many more moving parts than a quartz movement.
The Seiko/TMI NH family is widely used because it is robust, familiar to watchmakers and available in several configurations.
The official TMI NH-series technical information lists features such as hand winding, stop-seconds and 21,600 vibrations per hour across movements including the NH35 and NH38.
Luminius uses Japanese Seiko automatic movements in several mechanical wood watches. Haigh & Hastings uses Seiko NH35A and NH38 movements in models including its Classic and M2 ranges.
BOLDR has also used Seiko NH-family movements in its tool-watch catalogue. Melbourne Watch Company has used Japanese automatic movements alongside Swiss options.
Longevity
A serviceable mechanical movement can remain in use for decades if it is maintained and parts remain available.
Regular servicing becomes more important as lubricants age and components wear.
Durability
The NH family is a practical workhorse. Its comparatively straightforward architecture is part of its appeal in watches intended for regular use.
Accuracy
Automatic movements will normally vary more than quartz. Regulation, wearing habits, position and the individual calibre all affect daily performance.
Serviceability
This is one of the strongest reasons to pay attention to the calibre name.
Widely used movement families tend to be easier for watchmakers to recognise, service or replace than obscure movements with limited parts support.
High-Beat Japanese Automatic Movements. Miyota 9000 Series
Miyota's 9000-series movements sit in a more refined Japanese automatic category.
They run at a higher frequency than many entry-level automatic movements and are designed to fit relatively slim mechanical watches.
The official Miyota 9015 specification lists a 28,800-vibration-per-hour frequency, approximately 42 hours of running time, automatic and hand winding, stop-seconds and a stated accuracy range of -10 to +30 seconds per day.
BOLDR uses the Miyota 9015 in models such as the Odyssey MGP. Melbourne Watch Company has also used Miyota automatic movements in parts of its range.
Longevity
Like other quality mechanical movements, longevity depends heavily on servicing, lubrication and parts availability rather than the country printed on the movement.
Durability
The 9000 series is built for regular automatic-watch use, while a watch's case construction still determines how well the complete watch handles knocks, dust and moisture.
Accuracy
A 28,800-vibration-per-hour movement provides a smoother seconds-hand sweep and allows fine regulation, although it still will not normally match quartz for absolute timekeeping accuracy.
Thickness
This is an attribute buyers often overlook. A thinner movement gives the designer more freedom to create a slimmer automatic watch rather than a bulky case.
Swiss Automatic Movements: Sellita
Swiss automatic movements appear in several Australian-designed watches, particularly where brands want established mechanical architecture and strong servicing support.
Bausele says it primarily uses Swiss Sellita automatic movements. Its current Elemental models use the Sellita SW200, with a 38-hour power reserve and a 28,800-vibration-per-hour beat rate.
Adina also uses Sellita movements in parts of its automatic range, including newer Swiss-powered mechanical models.
Sellita produces a broad family of Swiss mechanical calibres. Its official movement catalogue is a useful reference when comparing specific movement families rather than treating "Swiss movement" as a single specification.
Longevity
The attraction of an established Swiss calibre is not that it is indestructible.
It is that a serviceable mechanical design, supported by parts and trained watchmakers, can remain viable for a long time.
Durability
Sellita movements are used across everyday, sports and specialist watches, but movement durability must still be considered alongside case protection and the way the watch is used.
Accuracy
Accuracy varies by calibre, grade and regulation. Bausele's published specifications show that even watches using the same SW200 family can be regulated to different tolerances.
Serviceability
This is arguably the most important long-term attribute of a mainstream Swiss movement.
A recognisable calibre and available parts can matter more after ten years than a small specification advantage when the watch is new.
Swiss Automatic Movements: Soprod
Soprod is another Swiss movement maker used in Australian independent watchmaking. Nicholas Hacko's Mark 1, for example, uses a Swiss-made Soprod M100 automatic movement running at 28,800 beats per hour with around 42 hours of power reserve.
Nicholas Hacko also notes that spare parts for the M100 are held in-house.
That is a useful reminder that the movement specification is only part of the ownership story.
Longevity
A mechanical watch's ability to stay in service depends on maintenance and access to parts. A brand that plans for future servicing adds practical value beyond the original specification sheet.
Durability
Mechanical movements need sensible care, but established calibres are designed to cope with ordinary wrist use when housed in a suitable case.
Accuracy
Like Sellita and Miyota automatics, Soprod movements operate within mechanical tolerances rather than quartz-level precision.
Parts support
For a watch intended to be kept for many years, this can be just as important as power reserve or beat rate.
Manual-Wind Mechanical Movements: Simpler Ritual, More Wearer Involvement
A manual-wind movement is mechanical but has no automatic rotor doing the winding for you. The wearer turns the crown to tension the mainspring.
Manual winding is less common in mainstream everyday watches, but it remains important in traditional and independent watchmaking.
Nicholas Hacko's work also represents the Australian artisan end of mechanical watchmaking, while Adina uses hand-wound movements in its pocket watches.
Longevity
A well-supported manual mechanical movement can be maintained for a very long period because its working parts can be serviced rather than relying on a sealed electronic module.
Durability
Removing the automatic winding rotor simplifies one part of the system, although the movement still contains a delicate mechanical gear train and escapement.
Accuracy
Manual winding does not automatically make a movement more or less accurate than an automatic. The calibre, regulation and condition matter more.
Wearer involvement
This is the defining attribute. Some people enjoy winding a watch as part of a daily routine; others will find it inconvenient.
Is Swiss Better Than Japanese?
Not as a blanket rule.
A Seiko NH movement, a Miyota 9015 and a Sellita SW200 are designed around different priorities and price points.
Country of origin tells you less than the actual calibre, its specification, how well it has been regulated and whether the brand can support it after the sale.
The same applies across the Australian brands in this guide.
Luminius uses Japanese quartz and automatic movements because they suit the balance of reliability, weight and value required across its wood-watch range.
Bausele leans into Swiss automatic movements. Adina uses quartz, solar and mechanical options. Haigh & Hastings spans Miyota quartz and Seiko automatic movements. BOLDR uses Japanese mechanical calibres in a number of its tool watches, while Nicholas Hacko operates at the specialist mechanical end of the market.
If you are deciding between the two broad movement types rather than individual calibres, our guide to automatic vs quartz watches covers the everyday ownership differences.
Which Watch Movement Should You Choose?
- Choose quartz if accuracy, low maintenance and easy everyday ownership matter most.
- Choose solar quartz if you want quartz convenience with less routine battery handling.
- Choose a Seiko/TMI automatic if you value a proven mechanical workhorse and broad service familiarity.
- Choose a Miyota 9000-series automatic if you want a relatively slim, higher-beat Japanese mechanical movement.
- Choose Sellita or Soprod if established Swiss mechanical architecture and long-term serviceability are priorities.
- Choose manual-wind if the ritual and mechanical connection are part of the appeal.
Frequently Asked Questions
Which type of watch movement lasts the longest?
There is no universal winner. A good quartz watch can run reliably for many years with battery and seal maintenance.
A serviceable mechanical movement can remain viable for decades when it is periodically maintained and parts are available. The quality of the complete watch and after-sales support matter as much as the movement category.
Which watch movement is the most accurate?
For ordinary wristwatches, quartz generally offers better absolute accuracy than mechanical movements.
Mechanical watches are chosen as much for engineering, craftsmanship and the experience of wearing them as for precision.
Are automatic movements more durable than quartz?
Not necessarily. Quartz has fewer moving parts, while a quality automatic movement can be repaired and serviced repeatedly.
Durability also depends on the case, shock protection, water resistance and how the watch is treated.
Why does movement serviceability matter?
A watch may be mechanically sound for years before it needs attention.
When that day comes, a recognisable calibre, available spare parts and a watchmaker familiar with the movement can make the difference between a straightforward service and a difficult repair.
The Bottom Line
Do not judge a watch movement only by whether it is Swiss, Japanese, quartz or automatic.
Look at the actual calibre and ask four practical questions: How accurate is it? How much maintenance does it need? Are parts and servicing available? And does the movement suit the way you plan to wear the watch?
Those answers tell you far more about long-term ownership than the country name alone.
