Watches that use the Tissot Swissmatic

The Swissmatic is Tissot's entry-level automatic, a close relative of the Swatch Sistem51. It appeared in the Everytime Swissmatic at the end of 2017 and then spread across Tissot's cheaper mechanical models. It's used only by Tissot, and every watch that has it says "Swissmatic" in the name, so it's easy to identify. Several of these models have since been dropped from Tissot's own US catalog, but they're common on the used market.

Specs at a glance

History and where it came from

In 2013 Swatch launched the Sistem51, a 51-part automatic built almost entirely by machines and sealed inside a plastic watch. It proved that a Swiss mechanical movement could be made at quartz-like prices. The obvious next step was to put that technology inside a more conventional steel watch, and Tissot did exactly that with the Everytime Swissmatic in late 2017.

The Swissmatic uses a near-identical architecture to the Sistem51 but has been adapted for Tissot. The most visible difference is the reserve: 72 hours instead of the Sistem51's 90. Tissot also fits it into steel cases with sapphire crystals and display backs, so you can see the skeletonized barrel and the plain, lightly finished rotor. Timetransformed described the finish as industrial, with a granular coating on the mainplate and a brushed rotor.

The idea was simple: give buyers a Swiss automatic with a three-day reserve for about the price of a quartz Tissot. For people who wanted "a mechanical watch" rather than a particular movement, it worked.

Accuracy in the real world

At launch, Tissot quoted accuracy of around ±10 seconds a day, with the potential to do better. Published tests back that up. Gear Patrol cited a Europa Star test that measured -4 to +2.5 seconds a day, and aBlogtoWatch's V8 Swissmatic ran at about -2 to -3 seconds a day. Those are single samples, but they're well inside the spec and better than many movements at this price.

Like the Sistem51, the Swissmatic is regulated at the factory as a finished module. There's no regulator arm and no practical way for a watchmaker to adjust it later. The rate your Everytime Swissmatic came with is, broadly, the rate it keeps.

Reliability and servicing

The Swissmatic is built to run for years without attention, and there's no known pattern of failures in owner reports. The difference from a normal movement is what happens when it does need work.

• No traditional service. Most of the movement is welded or soldered together, so it can't be stripped, cleaned and oiled in the usual way. Tissot replaces the whole movement instead. Gear Patrol expected that to cost less than a conventional service.
• No independents. Parts aren't available and the construction doesn't allow a rebuild, so an independent watchmaker can't do much beyond gaskets, crystal and case work.
• The case is serviceable. The caseback comes off, so gaskets and pressure testing aren't a problem.

Whether that's acceptable depends on how you see the watch. As a long-term heirloom, it's the wrong choice. As a well-made daily watch that you'll wear for a decade and then replace the movement or the watch, it's reasonable.

Quirks worth knowing

• Wrist-wound. Tissot sells it as self-winding and reviewers describe it as winding from wrist motion only, so don't count on the crown to fill it. (A 2014 review of the related Sistem51 found its crown would wind it when turned counterclockwise, but Tissot doesn't document this for the Swissmatic.) If your V8 Swissmatic has stopped, start it by moving the watch and then wear it.
• No hacking. The seconds hand keeps running while you set the time, so setting it to the second takes patience.
• Slow to fill from empty. Because you can't simply wind it at the crown, a fully stopped Swissmatic may need a good day or two of wear before it has anything like a full reserve.
• The date. Don't set the date late at night. Here's why.

How it compares

• Swatch Sistem51: the parent design, with a longer 90-hour reserve in a lighter, cheaper watch. Same no-service philosophy.
• Powermatic 80: the step up inside Tissot. It hacks, hand-winds, runs 80 hours and can be serviced, in watches like the PRX and Gentleman.
• Seiko 4R35: similar money in a Seiko 5 Sports or Presage. It hacks and hand-winds and any watchmaker can service it, but runs only 41 hours.
• Orient F6922: a cheaper in-house automatic that hacks and hand-winds, with about 40 hours of reserve.

Living with the 72-hour reserve

Seventy-two hours is enough for a normal weekend. Take your Everytime Swissmatic off at 6pm on Friday and, if it was fully wound, it will still be running on Monday evening. That's a big step up from the 40 to 42 hours of most watches at this price.

The catch is getting it full. Without a conventional crown wind, the reserve comes from wear, and a few quiet desk days won't fill it. If it does stop, you'll need to shake it to life, set the time without a hacking seconds hand, and then wear it for a while. That makes it worth knowing when it's close to stopping. Watch Winder counts down the Swissmatic's 72-hour reserve for each watch you own and reminds you before it stops. For a particular weekend, try the "Will my watch stop?" calculator.

Verdict

The Swissmatic does exactly what Tissot set out to do: a Swiss automatic with a three-day reserve and good out-of-the-box accuracy, in a steel watch at an entry-level price. The trade-offs are the same as the Sistem51's. It doesn't hack, it relies on wrist motion to wind, and it can't be serviced in the usual sense. If you want a watch to keep and service for decades, spend more on a Powermatic 80. If you want an easy, accurate daily automatic, the Everytime or V8 Swissmatic is a sensible buy, especially used.

FAQ

How long does a Tissot Everytime Swissmatic run off the wrist?

About 72 hours, or three days, from a full wind. If you haven't worn it much, it will stop sooner.

Can you hand-wind a Tissot V8 Swissmatic?

Not in the usual way. Reviewers describe the Swissmatic as winding from wrist movement only, so to start a stopped one, move the watch gently and then wear it.

Does the Tissot Classic Dream Swissmatic hack?

No. The seconds hand keeps running when you pull the crown out to set the time.

How accurate is the Tissot Swissmatic?

Tissot quoted about ±10 seconds a day at launch. Published tests have measured examples within a few seconds a day.

Can a Tissot Gent XL Swissmatic be serviced?

Not in the usual way. The movement is largely welded together, so Tissot replaces it rather than stripping and cleaning it. The case and gaskets can still be serviced.

Is the Tissot Swissmatic the same as the Swatch Sistem51?

It's closely based on it, with the same machine-built modular design. The Swissmatic is rated for 72 hours rather than 90 and is fitted in steel Tissot cases.

Is the Swissmatic the same as the Powermatic 80?

No. The Powermatic 80 is a conventional, serviceable movement with hacking, hand-winding and an 80-hour reserve. The Swissmatic is a sealed, machine-built movement that doesn't hack and relies on wrist motion.

Keeping it running

• On an average day an automatic gains roughly 4 hours of reserve per hour on the wrist, so about 18 hours of wear fills the Tissot Swissmatic. Desk days charge more slowly.
• Most automatics can also be wound by the crown. If yours has stopped, a few dozen turns gets it going before you put it on.
• Off the wrist it stops about 72 hours after it was last full. Stopped sooner?
• On a watch winder, start at about 650 turns per day, both directions. Winder settings for every movement.
• If it does stop, don't set the date between 9pm and 3am. Check if it's safe.
