Royal Oak 37mm V2 Case – Gunmetal
- In stock, ready to ship
Complete Your Build
The V2 Ultrathin Royal Oak case in gunmetal gray — a darker, matte-finish alternative to polished silver that avoids the scratch visibility of full black PVD. The gunmetal coating over 316L stainless steel gives the angular octagonal bezel and integrated lugs an industrial, tool-watch presence while maintaining the refined V2 profile at just 9.95 mm thick. At 37 mm diameter and 48 mm lug-to-lug, this case reads as understated and modern. Sapphire crystal with blue or clear AR coating, screw-down crown, 100 m water resistance. Compatible with NH35, NH36, NH38, NH70, NH71, and NH72 movements. Solid or exhibition caseback.

Why the V2 Ultrathin
The V2 Ultrathin in gunmetal occupies the middle ground between the bright silver and full black PVD finishes. At 9.95 mm thick, the V2 platform is one of the thinnest Royal Oak-style cases in Seiko modding, and the gunmetal coating adds a practical benefit: it hides light scratches better than both polished silver and black PVD. The matte gray tone sits close to the underlying steel color, so minor surface marks blend in rather than showing as bright lines (silver) or exposed steel spots (black PVD). For builders who want a darker case without worrying about scratch visibility, gunmetal is the most forgiving dark finish option.
