The details
The Hex FKM in navy is a deep, smart blue that's a great match for a blue-dial diver.
It's made from FKM, a fluoroelastomer rubber that's tougher and longer-lasting than ordinary silicone, and it holds its colour and shape well. The top has a hexagonal grid texture for a sporty, technical look, and cut-outs along the strap let a bit of air reach your wrist. It's flat, easy to rinse clean and narrows slightly towards the buckle. Quick-release spring bars come fitted, so you can change straps in moments without any tools.
It comes with a choice of gold or silver nickel-free buckle. Available in black, brown, navy, green, red, orange and yellow, from 18mm to 24mm.

What customers say about Hex
Read all 3 reviews →Ordered from WSS because they had a strap which I liked the look of at a reasonable price. Ordering was easy and I received it within a couple of days. The strap is well made and seems good quality. Overall, would recommend and will use again.
Good product at a very good price. delivery very quick. This the second time I have purchased from this company. Would recommend this company and their products.
Great quality strap and buckle, looks very cool on my inherited 1980s Seiko diver. Great value too and also no branding anywhere which is always nice, so big shout out to Watch Strap Style, will definitely be back for more!
