This watch is everything my submariner is not. I have served in combat and I wouldn’t hesitate to take this with me should I ever have to go again. In the last three weeks, it has run maybe +2 to +5 seconds per day. Have taken it hiking & trail running in the mountains along with a few weights workouts and it’s just great. Very lightweight, fits perfectly on my 6.75” wrist. Lume is as good or better than my new model submariner, even by morning.

I can wear this watch downtown without attracting negative attention in a flashy way, but I have also worn it with a casual blazer in a room of finance people and this watch was great with its unique style and heritage; definitely held its own.

The Silvermans sales team was outstanding, even despite the tariff complications at the moment in terms of shipping to the US. Customer service was top notch.

The only downside to this watch is that you (probably) can’t wear it in a formal situation but that’s really it. Can’t wait to take it all over the world with me.

Perfect watch

The most comfortable case I have ever worn, and have been lucky enough to own many of the top names in my lifetime. My first fixed lug watch. It is special. I received it on 4/1/25 and checking right now (6/5/25) it is 18 sec fast. (It arrived preset to my local timezone and within a second of on and on.). So I have never even loosened the crown after over two months. Yes, I also enjoy winding a watch at night, and wish this had the HAQ thermoline movement, but it is outstanding at what it is. Wish I had this during my 27 years active duty as a naval aviator. It would have traveled a long, long way with me.
