Is the COSC certification worth it over the standard Multifort TV Big Date?

Yes if accuracy matters to you. The chronometer version is independently tested across several positions and temperatures, and it adds the Nivachron balance spring. The standard version keeps the same look without that certification.

How does it compare with a Tissot PRX or a Christopher Ward?

The PRX offers a similar integrated bracelet look but no big date and no chronometer certificate. Christopher Ward competes on finishing and bracelet adjustment, while the Mido wins on the big date and certified movement.

It is rated to 100 m, which covers swimming and showering. The crown is not screw-down, so avoid diving and keep it away from high-pressure water.

How long does it run when I take it off?

About 80 hours, roughly three days, thanks to Caliber 80. That covers a weekend off the wrist without resetting.

The watch on its steel bracelet, a Mido presentation box, and the warranty and chronometer documentation. No extra strap is included.

Does the big date need special servicing?

The big date uses two discs, so it is more complex than a single-date movement. Have it serviced by Mido or an authorized watchmaker and avoid changing the date near midnight.

AccuracyPraisedBuyers report the COSC-certified movement keeps time well within chronometer limits.

Bracelet claspCriticisedReviewers note the folding clasp has no on-the-fly micro-adjustment, making fit tuning awkward.

About the Mido Multifort TV Big Date Chronometer

When every second counts, precision becomes essential. The Multifort TV Big Date Chronometer takes one of MIDO’s most distinctive designs to a new level as the first model in the collection to feature a COSC-certified movement. Its combination of certified precision and Big Date functionality is unique in its price segment. Powered by the Caliber 80 COSC, it offers up to 80 hours of power reserve and features a Nivachron™ balance spring for excellent resistance to magnetic fields and everyday shocks. Its sunray satin-finished dial features a rectangular chequerboard pattern, while redesigned indexes and a stepped flange with a minute track express precision in every detail. At 12 o’clock, an applied frame highlights the Big Date, while the stainless steel case offers water resistance to 10 bar (100 m / 330 ft).
