Gruppo Gamma Vanguard SteelvsResco Custom C9: DLC Gen2, Stealth UDT dial
The numbers, the dial colors, the calibers — laid out so you can stop flipping between tabs.
Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Movement accuracy is a notable strength, with one reviewer noting a -1.8 second per day deviation after initial testing. A weakness is the substantial price hike for the re-release model, which raises questions about whether the upgrades justify the cost. Reviewers disagree on the watch's originality, with one calling it "decidedly derivative" and the other not mentioning this aspect.
Owners widely praise the Resco's dial details, such as small 0.2-second indices and a trident second hand, along with its versatile, strongly cased, traditional diver look. Some owners note the bezel requires breaking in, and one experienced a significant financial loss on a return. Warranty repairs must be sent to the US. Overall, owners rate Resco highly for its distinctive dial elements and robust build, despite concerns about value and repair logistics.
