Set of two spring bars for modern Rolex 21mm × 1.5mm, in hardened Swiss Standard steel. Blind lugs. Size introduced by Rolex on the new-generation 40mm cases: Submariner 126610, Sea-Dweller 126600, GMT-Master II 126710, modern Daytona in certain variants.

21mm is the dimensional leap of 2020. Rolex moves from 20mm to 21mm to balance the new 41mm case — wider lug, better visual integration with the Oyster bracelet. The pin remains 1.5mm: the recess is blind and the geometry essentially identical to the 20mm. Only the length of the spring bar changes.

The same piece I fit in the atelier on all modern 41mm watches with 21mm lugs.
