Maybe on the expensive side but worth it looks perfect on my seiko sumo watch glad I made the purchase

Fantastic quality. Now comes with a couple of extra keepers to combat a flappy excess strap. Unbeatable for the price. Just amazing quality.

Excellent product. Fitted well and looks to be very durable. Would have given 5 stars if spring bars supplied had fitted.

A bit fiddly to attach but worth it. Sets off the watch nicely

These are good quality straps that fit the Seiko sumo perfectly, unfortunately I had to return mine as it had a slight manufacturer flaw. But this wasn’t my first crafter blue and 5 stars are given the fit and quality of these straps.

Very well made strap, hefty and plenty of adjustment even smelt nice.Unfortunately I just couldn’t get it to fit onto my Sumo and had to return it, I did receive a full refund so can’t complain. Sadly some theses straps can be hit and miss and I got a lemon.

I always go for metal bracelets but after seeing a picture of the Seiko with this strap, i knew i had to have one. The material is rugged and is so comfortable. Contrasts the green dial perfectly. Very easy fitting

Excellent strap. I bought this to go with the Seiko ‘Blumo’ and the blue strap works perfectly with the blue bezel. Easy to fit and comfortable, I’m pleased with my purchase.
