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 1968 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1968 Heritage Diver's Watch is widely praised for its excellent quality and finishing, with reviewers and owners noting its GS-level craftsmanship and Zaratsu-inspired polishing. Owners appreciate its refined design, comfortable case shape, and the 4:00 crown position, with some finding it more manageable on the wrist than other models. The Caliber 8L45 movement offers a 72-hour power reserve and accuracy within -5/+10 seconds per day, and the bracelet features an improved clasp with an extension system. However, some find the price point high, and one reviewer noted the unsigned winding crown as a missed opportunity. On balance, owners and reviewers rate the Seiko Prospex Marinemaster 1968 Heritage Diver's Watch highly for its premium finishing and tool-like appearance at its price point.
