I ain't gonna lie, that rubber strap is the bees knees. Can't go wrong with black, it's pliable, not too much vent at the lugs, and the material and fit is amazing. Plus, for summer time, it's the best for cleaning off. So I can do outdoorsy stuff with it and not stink up the NATO and leather.
But I think I'm going to test run the NATO, OEM rubber, and leather strap to see. It has to feel comfortable to.
Is the Uncle Seiko the same material as the OEM or more rigid?
Still contemplating a traditional, timeless oyster bracelet.
I like Barton Canvas straps. Tan strap would give it a weathered, military look
Speaking of canvas, I saw this canvas strap on someone's Seiko on Instagram and he told me he got it on eBay. It looked awesome. Thick, substantial, rugged, weathered, etc... It's only $14.99 on eBay with free shipping from a US seller. I think I might check it out. Bartons straps are really nice. I have a couple.
