Marathon Steel Navigator SSNAV-D AutovsStraton Straton Syncro Sports day/date Automatic

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.

Owners widely praise the Straton Syncro's exceptional finishing, retro design, and well-balanced dial, with one owner calling it Straton's best work. The fully-lumed dial is a significant draw for legibility, though one forum user notes the white dial's lume can cast a cool tone. Criticisms include a busy bezel design with difficult-to-read markings, applied numerals that reduce legibility, and a polished Milanese bracelet that contrasts with the brushed case. The NH36 movement is considered reliable but not highly accurate, and the 40mm case wears larger than its dimensions. The watch is approximately 15mm thick, which may present wearability issues with long sleeves. On balance, owners and reviewers highlight the Straton Syncro's impressive finishing and distinctive retro design as its strongest attributes.
