Spring bars modern Rolex 21mm × 1.5mm
€12,95
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.

Domande Frequenti
Which watches do these spring bars fit?
I fit them on modern Rolex models with a 21mm lug width: Submariner 126610, Sea-Dweller 126600, GMT-Master II 126710 and some versions of the modern Daytona. These are all new-generation 41mm cases.
What is the difference compared to 20mm spring bars?
The pin remains 1.5mm, the hole is blind and the geometry is the same. Only the length of the spring bar changes, to fit the wider lug.
Why did Rolex move from 20 to 21mm?
That is the 2020 shift: with the new 41mm case, a wider lug was needed, to balance the proportions and better integrate the Oyster bracelet.
How can I tell if my Rolex has a 21mm lug width?
Check the reference engraved between the lugs at 12 o'clock. If it is one of the modern 41mm models, the lug width is almost certainly 21mm.
What steel is it?
Hardened Swiss Standard steel. The same piece I use when a sturdy spring bar is needed for these cases.
