✅ Fits
Built to the same fat, shouldered double-flange spec used on classic Rolex Oyster bracelets, these bars are a direct match for drilled-lug Rolex models including the Submariner, GMT Master, Datejust, Oyster Perpetual, Daytona and Yacht-Master at your selected width. They'll also suit any other drilled-lug watch case (Rolex-style or otherwise) that calls for a shouldered spring bar between 12mm and 17mm.
⚠️ Please check your lug holes are drilled and sized for a fat, shouldered 1.78mm bar before ordering — standard slim spring bars (around 1mm) won't seat correctly, and non-drilled lugs won't accept this style at all. Confirm your exact width (12–17mm) before purchase, as each set is supplied in one size only.
