Hardened Swiss Standard steel. Pin diameter: 1.8mm. The 19mm size is characteristic of the early pre-Moon Speedmaster and certain Seamaster models from the Sixties and Seventies, before the definitive transition to the 20mm standard.\u003c\/p\u003e\u003cp\u003eOn the early Speedmaster reference 105.003 (Ed White) and the first 105.012, the lug is 19mm, not 20mm. The same specification applies to certain transitional Seamaster De Ville and Constellation models. The 1.8mm Omega pin is the factory standard for these cases — different from the modern 1.5mm Rolex. For aftermarket straps on Pre-Moon Speedmaster or vintage 19mm Seamaster, these are the correct spring bars.\u003c\/p\u003e\u003cp\u003eThe same spring bars on every vintage 19mm Speedmaster and Seamaster in the atelier.\u003c\/p\u003e","brand":"Milano Straps","offers":[{"title":"Default","offer_id":45432083185698,"sku":"MS-OMSB-NV-1819","price":12.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6461\/9298\/files\/milanostraps-rolex-spring-bars-vintage-modern-gmt-submariner-daytona-explorer_0c2455b8-246e-414b-8724-fdeb45b67dca.png?v=1779635304","url":"https:\/\/milanostraps.it\/en\/products\/spring-bars-omega-speedmaster-seamaster-19mm","provider":"Milano Straps","version":"1.0","type":"link"}
