Crown on the wrong side, on purpose
By Hannah Lindqvist, Stockholm ยท
The crown is on the left side of the case, and anyone who runs or skis with their wrist bent back knows why that's clever. No crown digging into the back of your hand every time you plant a pole.
EZM stands for Einsatzzeitmesser, roughly mission timer, and the 3F looks the part. Black dial, captive bezel, 200 m, a closed back. It's a tool and nothing else, and I respect that. Sinn doesn't try to make it pretty.
On a 15.5 cm wrist, though, it's a big tool. 41 mm, 11.6 mm thick, and 22 mm lugs with a wide leather strap. Leather is also an odd choice for something this purposeful. I'd want rubber. 38 hours from the Sellita is ordinary at 2,660 dollars and up.
For a firefighter, a mountain guide, someone with a big wrist who wants a no-nonsense instrument. Not me. But I'd happily borrow the left-hand crown idea for every watch I own.
