The YEMA Rallygraf Meca-Quartz pairs quartz-powered timekeeping with a mechanical chronograph module, giving it a smoothly sweeping chronograph seconds hand without making the entire watch mechanical. YEMA lists the original Panda at 39 mm and the Rallygraf II Reverse Panda at 40 mm; both cited versions have 20 mm lugs and a stated 100 m water-resistance rating. Those specifications make the Rallygraf a motorsport-styled everyday chronograph on paper, but they are manufacturer claims—not independent test results.
What “meca-quartz” means in the Rallygraf
The Rallygraf uses Seiko’s VK64 hybrid movement. YEMA says quartz powers the watch’s time functions, while a mechanical module controls the chronograph. The result is a quartz watch with a mechanically controlled chronograph and a smoothly sweeping chronograph seconds hand; it is not a fully mechanical watch. YEMA also lists a 32,768 Hz frequency and time, date and chronograph functions on its Rallygraf II product page.
The chronograph is the feature that gives the hybrid construction its appeal: you can start, stop and reset a timing function while keeping the convenience of quartz timekeeping. YEMA describes the movement’s construction, but the cited product information does not establish measured accuracy, battery life or long-term reliability.
Original Rallygraf or Rallygraf II?
The name covers more than one generation and dial reference. The two official listings below provide a useful comparison, but their specifications should not be assumed to apply to every Rallygraf colorway or configuration.

| Version listed | Case and dimensions | Crystal and bezel | Movement and water resistance |
|---|---|---|---|
| Original Rallygraf Meca-Quartz Panda | 39 mm diameter, 11 mm thick, 20 mm lugs; polished 316L stainless-steel case | Double-domed K1 mineral crystal; tachymeter bezel | Seiko VK64; 100 m water resistance |
| Rallygraf Meca-Quartz II Reverse Panda | 40 mm diameter, 11 mm thick, 20 mm lugs; 316L stainless-steel case | Double-domed 2 mm K1 mineral crystal; matte aluminum tachymeter bezel | Seiko VK64; 10 bar / 100 m / 330 ft water resistance |
Specifications are from YEMA’s listings for the original Panda and Rallygraf II Reverse Panda. YEMA Japan describes Rallygraf II as a full redesign: the case grows by 1 mm, lug and chronograph-pusher shapes change slightly, and the recognizable bi-compax dial arrangement remains. These details describe the generation-level redesign; exact finishes and features still depend on the reference.
Case size and wearing considerations
The one-millimeter difference is a specification, not a guarantee of how either watch will wear. The cited pages list 39 mm for the original and 40 mm for the II, with 20 mm lugs on both. If you are choosing between them, compare the particular reference’s case finishing, dial, and strap or bracelet as well as the diameter.

Dial and strap configurations
The cited listings show contrasting Panda and Reverse Panda treatments, with mesh-bracelet and Rallye-style leather-strap configurations. The II Reverse Panda listing also specifies Super-LumiNova BGW9 on the hands and markers. Check the exact listing for the configuration you want; a model-family name alone does not tell you which strap, finish or lume treatment is included.
What the tachymeter bezel is for
YEMA describes the aluminum tachymeter scale as a way to calculate average speed over a measured distance. In principle, time a known distance with the chronograph and read the scale to estimate average speed. That is an intended function, not evidence that the watch has been independently tested for timing accuracy or professional motorsport use.

Water resistance and practical limits
YEMA lists 100 m water resistance for both cited product pages, and gives the Rallygraf II figure as 10 bar / 100 m / 330 ft. Treat that as the manufacturer’s specification for those listings, not as a blanket promise for every water activity or every Rallygraf reference. The cited pages do not provide independent water-resistance testing or activity-specific guidance.
Design background and buying checks
YEMA says the Rallygraf takes inspiration from its vintage Rallygraf chronographs of the mid-1960s and identifies the checkered flag as a signature emblem since that decade. That is the manufacturer’s account of the design heritage; the cited information does not independently verify archival dates or stories about particular racing drivers.

Before choosing a listing, confirm the generation, exact dial reference, included bracelet or strap, seller, stock status and local price. A 20 mm lug width gives a starting point when considering another strap, but width alone does not establish fit: check the attachment style and the requirements of the particular reference. Prices and availability can vary by market and change over time. YEMA Japan displayed ¥72,600 for Rallygraf II while marking it sold out in the captured listing; that is a Japan-specific listing snapshot, not a current worldwide price or stock statement.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is the Rallygraf Meca-Quartz a good fit?
It is a plausible choice if you want a motorsport-inspired chronograph, prefer quartz timekeeping, and value a smoothly sweeping chronograph seconds hand. The original Panda and Rallygraf II Reverse Panda differ in case diameter and design generation, so choose by the precise reference and configuration rather than assuming the family name means every watch is identical.

The official specifications establish what YEMA lists, not how an individual watch performs over time. The cited evidence does not establish independent accuracy measurements, durability or reliability results, service costs, or battery life. If those factors determine your purchase, seek information specific to the reference and seller before buying.
