This OEM Omega Stainless Steel Bracelet is designed for the Railmaster and Aqua Terra models, featuring a 20mm size and a silver buckle.

Railmaster 20mm lugs Bracelet from just discontinued 40mm model from my personal FULL Set Dark gray slate dial I purchased at AD.
Highly desirable because of all three links brash and only few years of production , and most were sold on strange Jeans type cloth straps. But mostly desired by huge numbers of current 41 mm Aqua Terra model , as a replacement to shiny original bracelet.

I understand it’s a lot, but few REAL one And not fake for few hundred bucks were sold immediately for over 1100. Problem that this platform take $150 right away. I saw cheaper on chrono 24
