The Gruppo Gamma Vanguard Steel (ref. ag-10) is an automatic watch, with a 42mm stainless steel case, 12.6mm thick, powered by the Miyota 9039 movement and a 42-hour power reserve. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $790. The dial color is forged carbon.
The Gruppo Gamma Vanguard Steel is praised for its aged steel case and cream sandwich dial. However, some owners dislike the distorted sapphire crystal and the absence of minute markers, with one noting difficulty in replacing the crystal due to hand fitment. The watch features a Miyota 9039 movement with a 42-hour power reserve and an accuracy range of -10 to +30 seconds per day, and is offered with two strap options. On balance, owners value the Gruppo Gamma Vanguard Steel for its distinctive aged aesthetic and dial design, despite some reservations about the crystal.
