What people say

Owners + reviewers, side by side

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

Christopher Ward The Twelve 40 (Ti)

Christopher Ward The Twelve 40 (Ti) owners and reviewers highlight its high value, comfortable and lightweight titanium case, and COSC-certified Sellita SW300-1 movement. Some owners praise the finishing and textured dial, with one noting the sharpness of bracelet links is by design. However, a recurring point of criticism is the sharp edges on the bracelet links, with some also finding the inside surfaces of the clasp unfinished. One owner felt the dial appeared cheap for the price, while a reviewer desired more design originality in the dial and a micro-adjust system for the bracelet. Overall, owners and reviewers rate Christopher Ward The Twelve 40 (Ti) highly for its value and comfortable titanium build, despite some reservations about bracelet finishing and dial design originality.

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.
