The TMI VK63 is one of the most common movements behind affordable meca-quartz chronographs. It is popular because it combines quartz-powered timekeeping with a chronograph display that looks and feels more mechanical than a basic quartz stopwatch. If you are comparing a VK63 watch, the useful questions are not only “is it quartz?” but also what each subdial does, why the large center hand usually stays still until timing starts, how the reset works, and what trade-offs it has versus a fully mechanical chronograph.
This guide uses current technical information from Time Module (TMI) plus live Watchdives product data checked on September 18, 2026.
What Is the VK63 Movement?
VK63 is part of TMI's Premium Chronograph VK series. TMI classifies it as a quartz chronograph movement and lists Japan as the country of origin. The movement is 13½ ligne in size and 5.10mm high.
The feature set is more complex than a simple three-hand quartz calibre. TMI lists a center 1/5-second chronograph hand, chronograph minute counter, 24-hour indicator, small seconds and date. The movement uses an SR936SW silver-oxide battery, with TMI listing an approximate battery life of three years.

Why Is the VK63 Often Called Meca-Quartz?
The shorthand “meca-quartz” is used because the watch keeps time with quartz power while the chronograph is designed to give a more mechanical-style user experience. TMI highlights three characteristics of the VK series: an instant-zero-reset chronograph mechanism, click-feeling pushers and a center chronograph hand that advances in 1/5-second increments.
That does not make a VK63 an automatic or hand-wound movement. There is no daily winding requirement and no mechanical power reserve to manage. For ownership and maintenance, it should still be treated as a battery-powered quartz chronograph.
What Do the VK63 Hands and Subdials Do?
The layout can confuse first-time owners because the large center seconds-style hand is normally the chronograph seconds hand, not the continuously running seconds hand.
- Center chronograph hand: moves when the chronograph is started and displays 1/5-second increments.
- Small seconds: shows the continuously running seconds for normal timekeeping.
- Chronograph minute counter: records elapsed minutes while the stopwatch is running.
- 24-hour indicator: mirrors the main time on a 24-hour scale; it is not an independently adjustable GMT display.
- Date: the VK63 movement supports a date display, although an individual watch design may choose whether or not to expose every movement function on the dial.
So if the large center hand is stationary while the watch is keeping time normally, that is usually expected behavior rather than a sign that the movement has stopped.
How the VK63 Chronograph Operates
In normal use, one pusher starts and stops the chronograph and the other resets the chronograph hands after timing has stopped. TMI specifically promotes the VK series for its instant zero reset and tactile pusher feel.
The center chronograph hand advances in 1/5-second steps while timing. That gives the elapsed-seconds display a smoother visual motion than a conventional one-tick-per-second quartz seconds hand, while the underlying watch remains quartz powered.
As with any chronograph, use the exact watch instructions if the hand positions need recalibration after a battery change or an accidental input sequence. The case and dial manufacturer determines how the movement is integrated into the final watch.
VK63 vs a Fully Mechanical Chronograph
| Feature | VK63 meca-quartz chronograph | Fully mechanical chronograph |
|---|---|---|
| Power source | Battery-powered quartz | Mainspring |
| Daily winding / power reserve | No mechanical power reserve to manage | Required depending on movement and wear |
| Chronograph center hand | 1/5-second stepped display | Movement-dependent mechanical sweep |
| Reset feel | Instant zero reset is a highlighted VK-series feature | Movement-dependent mechanical reset |
| Routine ownership | Battery replacement plus normal watch servicing as needed | Periodic mechanical movement servicing |
The better choice depends on what you value. A mechanical chronograph puts more of the appeal inside the movement itself. A VK63 makes sense if you want quartz convenience but still want a more animated chronograph seconds display and a firm reset action.
Current VK63 Watches on Watchdives

Who Should Choose a VK63 Watch?
A VK63 chronograph is a practical match if you want:
- a battery-powered watch without an automatic power reserve to manage;
- a chronograph seconds hand with smoother 1/5-second motion while timing;
- instant chronograph reset behavior;
- multiple compact case options around 37–40mm;
- a lower entry price than many fully mechanical chronographs.
If the movement itself is the main collecting priority and you want a fully mechanical timing mechanism, a mechanical chronograph is the more relevant category. If reliability, convenience and a tactile stopwatch are more important, the VK63 is easier to own.
Frequently Asked Questions About the VK63
Is the VK63 automatic?
No. TMI classifies the VK63 in its quartz Premium Chronograph family. It uses an SR936SW battery rather than a mainspring.
Why does the big seconds hand on a VK63 not move all the time?
Because the large center hand is the chronograph seconds hand. Normal running seconds are displayed on the small-seconds subdial.
Does the VK63 sweep?
The center chronograph hand advances in 1/5-second increments while the chronograph is running. It therefore looks smoother than a one-step-per-second quartz hand, but it is still a quartz-powered chronograph.
How long does a VK63 battery last?
TMI lists approximately three years for the SR936SW battery. Real battery life can vary with usage, especially how frequently and how long the chronograph is operated.
Does VK63 have a GMT function?
No independent GMT hand is part of the standard VK63 function set. The 24-hour subdial is a day/night-style indicator tied to the main time display, not a separately adjustable second time zone.
Does every VK63 watch show a date?
The movement supports a date display, but the final watch design may not expose every available movement function. Check the exact dial and product specification before ordering.
Final Take
The VK63 is best understood as a quartz chronograph designed to deliver a more tactile and animated stopwatch experience. Its center 1/5-second chronograph hand, instant-zero-reset behavior, small seconds, 24-hour indicator and approximately three-year battery specification explain why it appears in so many affordable chronographs.
