You Must Own This Watch!

I've been wearing daily since I've purchased and I would say that this watch wears absolutely perfectly. My writs is on the smaller side, but the proportions and the nato comfort has made this such a great experience so far.

I would recommend though you buy more than one strap because of how versatile the watch is. I regret not buying the James Bond inspired nato, so don't make my mistake.

Would just add different strap color options, kaki notably

Great watch with history

I am happy with my RN diver. It is a sturdy toolwatch which has a story to tell. Annoying was the accuracy of the movement. Selitta top grade means -/+4 sec/day. Mine was -7sec, thus it needed immediate service. For this reason 4 stars.

I've been collecting much MORE expensive, automatic watches for some years and I was absolutely stunned to find such a GREAT and really affordable timepiece. It's a no-fuss, no-nonsense AUTOMATIC caliber, with 300m water-resistance and a generous amount of Superluminova (on which many more highly hyped and celebrated brands have apparently been saving a lot of money!) which makes it the PERFECT watch in any possible scenario.
It looks sleek, elegant and aggressive at the same time and I very proud to wear it.
The Nato strap is a bit too long for my wrist (17 cm), so I'd recommend to get an extra one (like the one I'm wearing in the picture), according to your needs.
Bravo CWC, keep up the good work!
