Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

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.

HELM Vanuatu

Owners widely praise the HELM Vanuatu for its exceptional comfort, with the titanium bracelet frequently cited as "uber-comfortable" and the watch itself being less overbearing on the wrist than comparable dive watches. Reviewers note its great bezel action and overall quality, with one owner finding the purchase satisfactory despite a nearly two-year wait. On balance, owners rate the HELM Vanuatu highly for its wearability and solid build at the price.

From video reviewers

The case finishing is consistently praised. The bracelet is noted as having significant rattle.
