High beat in a diver. Why not
By Tom Hargreaves, Falmouth, Cornwall ยท
36,000 vibrations an hour in a 300 m diver, which is a spec only watch nerds will care about, and I'll admit I'm a little bit one. The Ultra-Chron goes back to 1968 and Longines' early high-beat work.
43 mm cushion case, 14 mm thick, closed back, 52 hours, no date. At $4,600 to $4,900 it's a characterful thing, if a bit chunky. I'd rather have the Legend Diver for less.
