The problem

The industry spent a century designing for average wrists. Then it spent a decade shrinking.

We went the other way. A serious Swiss watch, built for the wrists that every 40mm forgot. No invented heritage. No whispering.
45mm
You'll notice it. So will everyone else.
904L stainless steel case, the grade most brands skip because it's harder to machine. Better in salt water. Worth it.

68h
Of power reserve. Roughly one long weekend of ignoring your phone.
Swiss La Joux-Perret G101 automatic. 24 jewels. Visible through the sapphire caseback, because there's nothing to hide.
300m
Water resistant. Your meetings rarely require it. Nice to know, though.
Screw down crown at 4 o'clock, so it never digs into your wrist. Sapphire crystal. Super-LumiNova on every hand and marker.
Black DLC bracelet clasp with the Moore mark

Five dials.
No wrong answer.

Because you already own enough black watches. The loud one, and the one people ask about first.

Fit

Built for the other wrists.

Most watches are drawn for a 17cm wrist. The Seasteel is drawn for 19 and up. It is not a cuff watch, and it was never trying to be. Honest numbers, not a mood.

Swiss made, plainly

Founded recently.
Zero heritage.
Excellent watch.

The movement is made by La Joux-Perret in La Chaux-de-Fonds. The watch is cased, regulated, pressure tested and shipped from Switzerland. The technical drawings are Swiss too.

That's the whole story. We'd rather you spent your time on the watch than on ours.
