Marathon Steel Navigator SSNAV-D AutovsYema Flygraf French Air & Space Force UTC Femme

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.

The Yema Flygraf French Air & Space Force UTC Femme is praised for its legible Type A dial, domed crystal, and chronograph subdials inspired by aircraft gauges, with a tricolore detail on the seconds hand and crown adding a unique touch. Its 40mm titanium case is noted for being lightweight and having a satin-matte finish. Owners appreciate the versatility with various strap types and the smooth, non-clicking UTC bezel. However, titanium's propensity to scratch more easily than steel is a concern, and one owner questions the purpose of the oversized crown. The in-house Calibre Yema2000 movement is regulated to +/- 10 seconds per day and offers a 42-hour power reserve, which is noted as lower than some competitors. On balance, owners and reviewers find the Yema Flygraf French Air & Space Force UTC Femme a versatile and legible tool watch, with its lightweight titanium case and aircraft-inspired design being key highlights.
