You can find the them here for half the price - 7.08US $ 27% OFF|16mm 18mm 20mm Pointed Deployment Buckle for Omega Rubber Leather Watch Strap Black Rose Gold Stainless Steel Butterfly Clasp|Watchbands| - AliExpressThanks for the reply. I think (emphasis on think) I finally figured it out. Found only one who ships to Israel for free (otherwise shipping is more than the price of the clasp!). Here is the link- would appreciate if you can verify best guess if this will work for my OEM Grand Seiko Skyflake strap: 16/18/20MM DEPLOYMENT BUCKLE BAND CLASP FOR OMEGA SEAMASTER PLANET OCEAN STRAP | eBay
It says it's made for OMEGA SEAMASTER PLANET OCEAN STRAP, and I think I have the size right at 16mm. What I really want is an upscale model that is reasonably priced and that has a good way of tucking a bunch of strap underneath. The seiko strap is exceedingly long on the long side with a ton of overhang, so it needs to be nicely secured underneath. THANKS!
In terms of a good quality versions - the best one is the OEM Omega version. All the other ones are comparable but just fall short of the OEM quality. I hope that helps.
By the way, this type of deployant would not work with your OEM Skyflake strap because there is a "fixed" keeper. Ideally you want straps that measure similarly (i.e, 100mm x 100mm in order for it sit nicely on the wrist). If you need pictures, I'll try to show you some.
