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.\u003c\/p\u003e\u003cp\u003e21mm 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.\u003c\/p\u003e\u003cp\u003eThe same piece I fit in the atelier on all modern 41mm watches with 21mm lugs.\u003c\/p\u003e","brand":"Milano Straps","offers":[{"title":"Default","offer_id":45432062410786,"sku":"MS-IT-MS-RXSB-MN-ST-1521","price":12.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6461\/9298\/files\/rolex-spring-bars-close-up-day-date-milano-straps_4c2c90d2-bed9-4512-a2e6-1ac3c044d0fe.png?v=1779634152","url":"https:\/\/milanostraps.it\/en\/products\/spring-bars-rolex-moderno-21mm-15mm","provider":"Milano Straps","version":"1.0","type":"link"}
