What We Know

It’s a big day for ana/digi fans out there – aka me and my friends – as the Canadian brand Momentum has just announced a modern take on the cult classic Chronosport UDT.

That water resistance is ensured via a screw-down crown and a pair of screwed pushers, so don’t forget to screw them down before you dive. The Monnin-style case is set with a closed caseback, but the modern UDT benefits from a matte ceramic bezel insert (showing an elapsed time bezel).

The movement offers the usual host of digital-derived features, including a second time zone, a …read more
