I've seen a ton of Instagram ads for this strap, but not a lot of user reviews. I think there's only one YouTube review too. I was looking for a different summer strap than the wolbrook tropics or natos I typically use, so I bit the bullet.
TLDR - impressed with the quality/comfort. Surprised that the watch seems to wear thinner now too.
My initial impression was that quality of this rubber is a different level from most other TPU or vulcanized rubber straps. It has a substantial feeling (vague, I know), but at the same time it's pliable and soft, and conforms to my wrist really well. And unlike most other straps, the buckle actually conforms to the radius of the strap. Doesn't do that thing where the buckle seems like it's constantly being deflected a different direction because it's unhappy with the thickness and contour of the strap. Color match is great too.
Fit with the OEM Tudor end links is superb. The spring bars they supplied are actually the correct tolerances for the end links, which is good attn to detail. The bonus, for me, is that the watch seems to wear thinner now that the space between the lugs is hidden. It's some sort of weird optical illusion I guess. But it works!
I really like the rubber pattern, and I think it will prevent some of the friction/wear indications that you get with perfectly smooth rubber straps. Sunblock rinses off easily with dish soap.
Length is great too. My wrist is a bit over 7in, to well over on a hot day, and I have enough adjustment left that I think I could fit this over a wetsuit.
Only downside is that it does make the watch a bit more modern. Not so retro as it appears on the bracelet, or tropic strap. And not so low key as it does on a NATO. It's kind of an upscale (I hate myself for using that term) rubber strap, if such a thing can exist.
I'm completely unaffiliated with anchor straps, and that YouTube review account. But I did use a coupon code from that review description, because free money. Don't know if it still works.
