The HM2 SV Black is a special limited edition within the HM2 range: “SV” stands for Sapphire Vision. This piece explores the limits of sapphire crystal in case design.
The HM2 SV Black case is composed of a PVD coated titanium base topped by sapphire crystal. Machining and finishing of sapphire crystal is extremely challenging; many cases were destroyed during the delicate production process. The striking green outline around the rectangular case is functional: this is in fact the gasket that guarantees water-resistance to 3 atm. The green of the gasket matches the green of the winding rotor of the automatic movement.
The HM2 movement is one of our most complex in terms of horological complications: on the left dial, “slow time” displays a retrograde date and a bi-hemisphere moon phase. On the right, “immediate” or instantaneous time: jumping hours in the centre, surrounded by retrograde minutes.
The HM2 SV Black edition was limited to only 18 pieces.
