Long story short, I would like to buy a seat belt Nato for my Speedmaster of which the buckle could be easily replaced (with a Bergeon tool) by an Omega one. Which Natos are the most suitable for this task?
For the ones I've tried out, from what I think would be easiest to hardest:
The Crown & Buckle supremes, Moose Strap Co. slim versions, ToxicN8O seatbelt line, and BluShark AlphaShark slims are the ones that use a springbar-retained buckle, if I remember correctly. Don't have my NATO strap collection in front of me to verify though. The C&B, Moose slim, and ToxicShiznit appear to use the same type of fabric (potentially from the same factory?), which is quite nice, but very slightly thicker than a standard NATO. The BluShark AlphaShark slim seems to use the same type of fabric as the WatchGecko seatbelt NATO, thinner but smoother than the C&B/Moose/ToxicShiznit.
The Phenomenato has a thin sleek one-piece buckle that is sewn in, which you could cut through with wire cutters or sheetmetal shears. The fabric on this one is probably the closest to the luxury Omega NATO, from reports of those who have owned both.
Cincy Strap Works "regular SB"s and WatchGecko's seatbelt NATOs use the same run-of-the-mill NATO strap buckles, which you could probably get through with a decent wire cutter, but I'd probably not try a lightweight metal shear on them.
The BluShark AlphaSharks standards, Cincy Strap Works thick "Premium SB"s, Moose Strap Co. non-slim version, and Strap Mill Canada seatbelt lines, all have hefty one-piece buckles sewn in, and thick fabric. I think the Haveston buckles are also one-piece as well, and also pretty thick. You'd probably need heavier-duty wire cutters to get through them.
