It looks like this comes in 2 sizes, 19-20mm and 20-21mm. Is that true? If so how would i know which one fits a 41mm last gen SMP?

Either. Those are 20mm I believe. I’d rather go the bigger with curved bars available from Omega.

 

They come in 19-20 and 21-22 (not 20-21). For reference, here’s the 19-20mm on the SMPc.

 

What exactly are those measurements for? So both sizes work on all seamasters?

 

Then 19-20 on reg springbars.

 

Anyone know the answer to this?

 

The 19-20 are made for watches with 19mm and 20mm lug widths. The 21-22 are made for watches with 21mm and 22mm lug widths. For your Seamaster, you should get the 19-20 since it has a lug width of 20mm. Both sizes do not work on all Seamasters.

 

Excellent, thanks!

 

I love the quality of the NATO that came with my Speedmaster but compared to a real military NATO the metal keepers are placed incorrectly & don't fit me correctly (ie with enough material to fold back through both the keepers).
My CWC NATO is 297mm & is a better fit (ie with no flapping strap end) than the Omega NATO at 305mm.

 

Honestly I may not even get one. I really want to do this look but its hard for me to justify spending $350 on a dang strap. I wonder if theres any cheaper knockoffs.

 

Don’t know where you’re getting the $350 price from on these. I bought mine for $180 from a boutique just last year. Unless the price has doubled in the last year, $350 is way too high — perhaps these are the marked up prices you find on EBay?

 

Just checked the US Omega site and that strap you pictured sells for $160 and you get a free strap change kit if you order online — that includes a nice padded case, a high-quality spring bar tool, and extra spring bars.

 

So I was actually looking in the wrong place. I didnt realize you could order it through their site. People are marking these up like crazy online because not everyone is that close to an AD or boutique, and Im not either. Thats why I was looking elsewhere online.

 

Yes any number Though technically Omega is the knockoff The original British military straps are made by Phoenix & are a lot cheaper though they're not available in Carlos Fandango colours ..

 

Omega NATOS are not a knock-off. It is inspired by the G10 design as specified by the MoD. There are many differences between the Omega and Phoenix NATOS. Phoenix is the official supplier of the HRM. The fabric of the Phoenix is really woven with a high density webbing. But it is a lot thinner. The fabric of an Omega strap is 1,4mm thick whereas the fabric of a Phoenix straps is 1,0 or 1,2mm. The hardware is stitched on the Omega strap while heat welded with the Phoenix ( as requested by the MoD in in the defStan of 1973). The Omega strap has a thicker buckle than the Phoenix etc. Omega NATOs are nice but really expensive for what they are. Tudor makes also NATO straps for comparison of which some are woven with a natural silk thread on old school vintage machinery in France.

 

Which are a knock off of earlier straps... as 1964 Bonds “NATO” predates the “G10” MOD spec from 71 ordered with form G1098. So if your going to be pedantic

 

We could chase this around for ages & find points that support both views. As a young rifleman my G10 watch had a strap made by Phoenix. I have an Omega NATO, a thing of beauty that doesn't fit properly because Omega have put the keepers in the wrong positions - wrong being defined by the MOD specs. Put the two together & the difference is clear. I'm sticking to the view that MOD/Phoenix/ CWC is original but I'm not knocking the quality of the Omega (as seen in my avatar), I just wish they'd followed the MOD spec for spacing the keepers so I could actually wear the thing!

 

If only the lovely Tudor NATOs were available for other brands. The only NATO straps I've ever worn and liked. With the standard NATO I can't stand the bunch of unneeded material you get in the 12 o'clock keeper. If you wear them RAF style then there's nothing to stop the head rotating into the wrong position.

I bet there will be Tudor style knock offs available somewhere soon.

 

My Omega strap has adjustable keepers and it set up so the buckle is on the bottom of my wrist not the side like most. I’ll stick to my custom three rings though.

 

My Omega strap has a flap of leftover material that's too short to reach the second keeper (the one nearest the watch head) & so short that when fed back into the first keeper it won't stay in - despite being longer than my Phoenix one. I'm sure it's down to the buckle position & the spacing of the keepers (one is free floating but the other is fixed).
