I have had the Crafter Blue curved end straps on my SRP777 Turtle and on my SBDC033 Sumo for a number of years. Even though they fit beautifully on the watches, initially, I did not like the straps all that much as they were quite tough and not all that pliable. Having worn them ‘in’ for a few years now, and having ditched the metal keepers they used to have, I have to say that the Crafties are now my favourite rubber straps by far. They are much more flexible and hug my wrist just enough to keep the larger Seikos in place, breathing well enough to avoid sweatiness. They were not cheap; but, like good leather, just get better over time.
Thumbs up for "dimensionality"! ;) Have you tried the FKM rubber straps from Aliexpress? I was shocked at how nice they seemed (wen they finally arrived...), and wonder how much better the *much* more expensive ones like these are?
...... I bought a Crafter Blue strap but unfortunately didn't realise they have a strong vanilla aroma , which they don't mention on their website .... some folks seem to like it ........ sadly not I , just can't wear the strap as the aroma is so strong...... beautifully made though .........
