Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's WatchvsTissot Seastar 2000

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.

Owners widely praise the Tissot Seastar 2000 for its impressive specifications at its price point, including an 80-hour power reserve, ISO 6425 certification, sapphire crystal, ceramic bezel, and 600m water resistance, with its dial quality and finishing considered superior for its class. The blue dial is frequently highlighted as particularly sharp and legible. However, the watch's substantial size and weight are consistent drawbacks; its 46mm width, 16.3mm thickness, and 52mm lug-to-lug dimension make it too large for some for everyday wear, with a rubber strap often recommended over the metal bracelet for comfort. A significant concern raised by multiple owners is the bezel's tendency to become loose and lose its click, with one reporting this on two separate watches. Accuracy figures vary, with one owner noting +1 second per day and another around +5 seconds per day.
