What people say

Owners + reviewers, side by side

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

Beaufort Pulsatimer

The Beaufort Pulsatimer is praised for its solid manual-wind Sellita SW510M BH b movement and remarkable value, with one reviewer noting a 63-hour power reserve. Its 39mm case features dynamic, layered finishes and piston-style pushers, blending vintage dressiness with a robust chronograph design. Some find the optional beads-of-rice bracelet too much for its aesthetic. Overall, owners and reviewers rate the Beaufort Pulsatimer highly for its unique design and strong value proposition.

Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
