Excellent FKM Strap!!! This was my second strap from Anchor! Highly recommended for your timepieces.
B
Awesome FKM single pass strap! I love the blacked out strap on my PVD coated day date CWC diver. Definitely the most comfortable strap i’ve worn because of it’s thinness but durable design. It’s great for when your wrist swells from the heat!
D
I discovered Anchor Straps on my IG feed and went to their website several times looking at various straps for my RESCO Kauffman. I decided on a Single-Pass FKM Rubber Strap in Black. I have had the strap on my watch now for about a week and find it very comfortable and secure. Also great value for the $$ spent.
C
Absolutely everything you hope it will be and more! Super impressed with this strap. It's soft, yet strong and durable. Super comfortable on the wrist. Really nice and well designed buckle as well.
