Of late I have become rather enamoured of ZULUs and the NATO/G10 watch straps. I think the NATOs are a bit more comfortable, but I like the look of either. I have a Citizen Eco-Drive ProPilot with (Stupidly IMHO) 23mm lug width so I have bought straps at 22mm and 24mm to try (FWIW, IMHO 24mm is better, so go up in size not down). And I have bought a Marathon TSAR (Christmas present to Me). I've tried a 22mm strap on it, I think 20mm is thinnish, but the real size, ie. 20mm, works better.
So I'm looking at these straps at between $16 and $28 each and thinking I'd like to try several strap colours, ZULU and NATO, but don't want to spend a couple of hundred dollars doing that. After a bit of search, got on to ALIExpress where there are thousands of ZULU/NATO straps ranging $1 to about $5. Ended up finding ones for $1.82 each and bough four ZULUs and 4 NATOs. They arrived today. Now these are not $200 Omega NATOs, but, TBF they seem reasonable. The seams are stitched (I saw that in the ad), the size is the same as my other straps, the Ballistic nylon is a little thinner (actually a good thing) and the hardware is stainless steel, not 5 star, but certainly 3.5 to 4 star. Anyway, I've tried several colours already and the straps fit nicely and look OK. I've picked fairly basic, solid colours because that's what I like, and I'm sure these guys will outlast me. And I spent all of $14.52 on eight (8) straps.
The $17 Zulu is highlighted in the picture below for a quick comparison
So not saying don't go and buy good quality (and somewhat more expensive) NATOs and ZULUs, but if you want to see what those expensive straps might look like before you buy, this is a cheap option (and I'm happy with these straps regardless).
Of course, YMMV...
