{"product_id":"spring-bars-rolex-sea-dweller-1665","title":"Spring bars Rolex Sea-Dweller 1665 — 20mm Double Red","description":"\u003cp\u003eSet of two spring bars for Rolex Sea-Dweller reference 1665, in hardened Swiss Standard steel. Size: 20mm between the lugs. Pin 2.0mm. Drilled lugs. The 1665 is the first Sea-Dweller, produced from 1967 to 1983 — the celebrated Double Red (DRSD) and then the Great White, the first Rolex watch conceived for deep diving with a helium escape valve.\u003c\/p\u003e\u003cp\u003eThe 1665 operates at 610 metres (610m = Sea-Dweller). A case thicker than the Submariner, tall Plexi crystal, helium escape valve on the flank at 9 o’clock. Drilled lugs, 2.0mm pin — the geometry is that of the vintage Submariner but calibrated for professional underwater loads. A leather strap on a 1665 works, but the spring bars must be the right ones.\u003c\/p\u003e\u003cp\u003eThe same piece I fit on 1665s in the atelier.
