What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Boldr Odyssey Regatta

The Boldr Odyssey Regatta is noted for its robust functionality and utilitarian design, powered by a Valjoux 7750 Elaboré movement. It features a tachymeter bezel graduated in knots and offers 500m water resistance. While its 45.5mm diameter, 18.2mm thickness, and 245g weight make it a substantial timepiece, it wears better than its dimensions might suggest. Overall, owners and reviewers highlight the Boldr Odyssey Regatta's workhorse movement and functional tool-watch capabilities.

From video reviewers

500m water resistance is a consistently praised feature. The watch's significant weight and large case size were noted as drawbacks by multiple reviewers. Reviewers disagreed on whether the bezel's 15-minute markings were redundant given the regatta complication.

Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition

The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, with a new grey bezel insert and a wave-patterned silvery-white dial. Owners find the watch attractive and the large case wears well without feeling bulky. However, some consider the price of €1900 for a 6R54 movement with an accuracy of +25/-15 seconds per day to be too high, and the production run of 6000 units is not seen as a true limited edition. Overall, owners find the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with good wearability, but express concerns regarding its value proposition and movement accuracy for the price.
