Artime ART02: the case becomes part of the movement, with two kinds of seconds

In the ART02 Rostovsky/Cellini Edition, a red hand jumps every five seconds to reveal the constant-force remontoir at work. The edition comprises 12 pieces.

Why it is interesting

The ART02 reveals constant-force operation through the hands’ movement. Its complex mechanism is observable, and the case genuinely participates in the movement’s structure.

Things to consider

Sources differ on dimensions for the special edition and general ART02: 39 versus 40 mm. Confirm the ART02-TI-CR specifications and price with its partner before ordering.

The model in detail

Meet the watch

The Artime ART02 does not allow the usual boundary between case and movement. Its titanium-and-sapphire construction was developed as one system: there is no traditional mainplate on which to assemble the calibre. The case participates in its structure. Transparency is therefore connected to the watch’s engineering itself.

The central technical feature is a constant-force remontoir. It periodically supplies portions of energy to the regulating system, reducing dependence on how fully wound the main barrel is. In the ART02, its operation involves a Reuleaux triangle. Two coaxial seconds hands make the process observable: the white hand shows running seconds, while the red hand jumps with every five-second cycle.

The power-reserve indicator is unusual too. A white hand shows remaining energy, while the red hand can be positioned as a reference on the circular scale. The manufacturer connects their meeting after approximately 80 hours with the end of the range in which the remontoir operates under its specified conditions. The important figure is the chronometric reserve—the period of regulated energy delivery, rather than an abstract number of hours.

Details and limitations

The Rostovsky Watches and Cellini version is distinguished by a golden bridge and limited to 12 pieces. For the ART02-TI-CR, Cellini specifies a 39 × 9.5 mm case, hand winding, 3 Hz frequency and 30 m water resistance. The manufacturer’s general ART02 page gives 40 mm, so the special edition’s dimensions here follow its partner’s listing.

The current reason for this review is the edition’s exhibition debut at WatchTime New York on October 16–18. The version had already appeared in the organiser’s September 3 preview. Sales are exclusive to the two named partners; no public price appears in the verified listing.
