{"product_id":"spring-bars-rolex-sea-dweller-16660","title":"Spring bars Rolex Sea-Dweller 16660 — 20mm Triple Six","description":"\u003cp\u003eSet of two spring bars for Rolex Sea-Dweller reference 16660, in hardened Swiss Standard steel. Size: 20mm between the lugs. Pin 2.0mm. Drilled lugs. The 16660 is the second Sea-Dweller, produced from 1978 to 1989 — nicknamed Triple Six for the 1220m (4000ft) depth and the three 6s engraved on the caseback numbers.\u003c\/p\u003e\u003cp\u003eThe 16660 is the technical leap between the 1665 and the 16600. Sapphire crystal in place of Plexi, doubled depth rating, revised helium escape valve. The lugs remain drilled until the end of production: 20mm × 2.0mm. For those who collect vintage Sea-Dwellers, the 16660 is the midpoint between the earlier 1665 (rare, expensive) and the modern 16600 (more accessible). The right spring bars are part of doing the work properly.\u003c\/p\u003e\u003cp\u003eThe same piece I fit on my clients’ 16660s.\u003c\/p\u003e","brand":"Milano Straps","offers":[{"title":"Default","offer_id":45432071651362,"sku":"MS-IT-NS-RXSB-VG-ST-2020","price":12.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6461\/9298\/files\/rolex-day-date-watch-spring-bars-milano-straps_eefacb3f-9c8a-4ae4-9f79-51fcd2cd7c8a.png?v=1779634566","url":"https:\/\/milanostraps.it\/en\/products\/spring-bars-rolex-sea-dweller-16660","provider":"Milano Straps","version":"1.0","type":"link"}
