{"product_id":"spring-bars-rolex-day-date-18038-oro","title":"Spring bars Rolex Day-Date 18038 yellow gold — 20mm","description":"\u003cp\u003eSet of two spring bars for Rolex Day-Date reference 18038 in 18-karat yellow gold, in hardened Swiss Standard steel. Size: 20mm between the lugs. Pin diameter: 1.8mm. For the entire 18038 production, from 1979 to 1989 — the first Day-Date with a quickset case and 3055 movement.\u003c\/p\u003e\u003cp\u003eThe 18038 has drilled-through lugs, even in the earliest production. 1.8mm pin — not the modern 1.5mm and not the vintage 2.0mm. It is a compromise chosen by Rolex for the gold cases of the late Seventies: 18k gold is soft, a hole that is too wide deforms under load. The 1.8mm holds better in the seat without becoming oval.\u003c\/p\u003e\u003cp\u003eWhen I work on an alligator strap for a client’s 18038, these are the spring bars I fit. The correct specification for the gold case.\u003c\/p\u003e","brand":"Milano Straps","offers":[{"title":"Default","offer_id":45431895982114,"sku":"MS-IT-MS-RXSB-VG-DD-36","price":14.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6461\/9298\/files\/rolex-watch-spring-bars-set-milano-straps.png?v=1779630175","url":"https:\/\/milanostraps.it\/en\/products\/spring-bars-rolex-day-date-18038-oro","provider":"Milano Straps","version":"1.0","type":"link"}
