GS Sapphire black.

I can only agree with previous reviews of this watch. It is well made in every way and its good to know you have something so reliable strapped to your wrist. It is by no means a fancy, attention grabbing watch but simply does what it is supposed to do in a very confident and professional manner. Perfect for working people who need a rugged and reliable watch in harsh conditions. Well recommended 200m waterproof and sapphire crystal watch.

Black watch

Received it in Colorado in 4 days and time was set precisely to my time zone 👍.
The 36mm size is perfect on my 7” wrist and legibility is outstanding. The bold white numerals jump out on the all black case and dial. I like the fixed bars but they’re a little tight on some straps. Really liking this watch.


This is my new grab and go watch. It’s the most comfortable watch I own. I wanted a dateless quartz watch that you can just set and forget and this delivered. Sometimes I get tired of setting an automatic if I haven’t worn it. I’m usually into slightly bigger watches but the size adds to its comfort and it doesn’t feel dainty in the least. I love the PVD coating and the brushed steel hands. It’s top notch quality in every aspect and the legibility is perfect in all lighting. This is the perfect field watch with better specs than most on the market. This watch can go everywhere from the field to the beach and the long lasting battery is another great touch. There were reviews here that said the strap wasn’t the best, but I have zero complaints. I’ve owned all sorts of watches from Marathon, Hamilton, Seiko, Citizen, Traser, and Bertucci. The GS Sapphire contends with the best of the best. Thanks CWC for making a quality, purpose built watch that will get its use for years to come.
