HUB1280 Unico

Probable

The Unico is Hublot's own, and it carries a genuinely unusual feature that is also the best check on it: the column wheel is mounted on the DIAL side, visible through the skeletonised dial without opening the watch. Watching the column wheel index as the chronograph is started confirms both the caliber and that the chronograph is doing what it appears to. Two further bench tests: it is a flyback, so reset while running restarts from zero, and the reserve is roughly three days against the HUB44's not-quite-two.
