One of the most distinctive versions of Cartier’s signature rectangular watch, the Tank à Guichets has been revived as part of the Privé collection, joining watches like the Tortue Monopoussoir and Tank Cintree. The last time Cartier had such a model in its catalogue was exactly 20 years ago with the Collection Privée Cartier Paris (CPCP) iteration.

Sporting a crown at 12 o’clock like some historical examples of the model, the Tank à Guichets indicates the time in twin apertures, with jumping hours at 12 o’clock and minutes at six. Measuring a slim 6 mm in height, the Tank à Guichets (or “Tank with Windows”) is powered by a new in-house movement, the cal. 9755 MC. Notably, it will be a regular production model in yellow or rose gold, as well as platinum, plus an asymmetrical or “oblique” model that is limited to 200 pieces.

Initial thoughts

The Tank à Guichets was always one of my favourite iterations of the Tank, and the popularity of the preceding version made it almost inevitable that Cartier would revive the design. The new Tank à Guichets is subtly different from the CPCP version, most notably in its slim profile, but still looks and feels correct.

The finishing on the case is excellent, particularly on the polished bevels that frame the apertures. The movement, on the other hand, is concealed behind a solid back but is industrial in finish and style. That said, it is an integrated calibre – the jump hours is part of the base plate – which is a plus.

The Tank à Guichets starts at €43,000 in gold, rising to €55,000 for the “oblique” edition. It is steep for a time-only watch with a fairly basic movement, but in the context of a highly-priced market overall, unavoidable.

As an aside, the “oblique” version is undoubtedly the most interesting, but the execution feels little half-hearted as the discs for the time are identical to those on the regular models. As a result, the hour numeral is 90 degrees off the vertical; fixing that would have been an easy matter of printing a new hour disc.

Windows

The Tank à Guichets returns to the format of the original model that debuted in 1928, nine years after the original Tank (which was a Normale), hence the crown at 12 o’clock. This sets the watch apart from the CPCP versions, which had a conventional crown at three.

The rest of the watch is similarly traditional, with twin windows on a brushed front panel that indicate the time. Each of the windows is in a bevelled frame that is finished in same manner as a movement – the edges are rounded and mirror polished in a technique known as anglage.

The hours disc is jumping, moving one step at the top of each hour, while the minutes below are “dragging”, constantly rotating.

Unlike the prior version of the model, the new Tank à Guichets is powered by an in-house movement, the manual-wind cal. 9755 MC. It’s an entirely new calibre created for the model with an integrated jump hour mechanism, though it is based on the architecture of Cartier’s longstanding workhouse movement.

Like many of Cartier’s recent movements, the cal. 9755 MC is industrial in style and finish as revealed by the milled decoration and Etachron regulator index.
