Pin diameter: 1.8mm. Correct size for Speedmaster Professional, Seamaster 300M (drilled and closed lugs), Aqua Terra 38, recent Railmaster.\u003c\/p\u003e\u003cp\u003eOn the Speedmaster Pro, the 20mm with 1.8mm pin has been the factory specification for decades. The Moon case is tight on the lugs: with an undersized pin, the strap shifts by a millimetre with every movement. It doesn’t break, but you feel it. And a strap you feel is a strap made badly.\u003c\/p\u003e\u003cp\u003eI fit them on the Speedmaster leather straps every time I stitch one. It is the standard size for the most widespread wrist in the world.\u003c\/p\u003e","brand":"Milano Straps","offers":[{"title":"Default","offer_id":45431867572258,"sku":"MS-IT-MS-OMSB-NV-1820","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_fa28fa5a-d461-4245-9b3e-3e854d5e99c3.png?v=1779628748","url":"https:\/\/milanostraps.it\/en\/products\/spring-bars-omega-20mm","provider":"Milano Straps","version":"1.0","type":"link"}
