Marathon OSAR-D (Original SAR with Date) Automatic 41mm

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose. Its Swiss-made Sellita SW200-1 movement is considered reliable and serviceable. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.

Grand Seiko SBGH347

The Grand Seiko SBGH347 is lauded for its refined 37mm Ever-Brilliant Steel case, impressive Zaratsu polishing, and classy ice-blue dial inspired by frozen waterfalls. Its Hi-Beat 9S85 movement is a significant draw, and the framed date window is preferred over a cyclops. Reviewers note the bracelet lacks micro-adjustment or a quick-change system, and some wished the 13.3mm thickness was slightly thinner on the compact case. Overall, reviewers praise the Grand Seiko SBGH347 for its elevated finish and value, with the Hi-Beat movement being a significant draw.
