I'm new to the watch world and just purchased my first reasonably nice piece, a Squale 1521 with the blasted finish. I didn't like the strap it came with aesthetically (I think a leather strap looks off on a diver) and functionally (I exercise 2 to 4 hours / day and in the AZ sun, the leather isn't great). I tried a rubber strap from Uncle Seiko, and it was an improvement over the leather, but hard to get a good fit. I tried a couple NATO straps and found them annoying to adjust on the fly. Then I found out about Nick Mankey straps. After doing some research I ordered one for myself (in orange) and one for my dad (for his MKII Cruxible Hellion, in black and grey). They both arrived, and gosh are these straps nice. The design is enormously comfortable and very easy to adjust on the fly -- much easier than a traditional strap or a NATO. It's also very breathable (I just got back from a 10 mile run in >100F weather, while wearing the watch, with zero issues). The fit and finish is fantastic. I really couldn't be happier with my purchase. I'm sure I'll buy more Nick Mankey straps in the future. 10/10 would reccomend!
