What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional thinness, with multiple sources noting profiles between 10.4mm and 11mm, comfortable wearability on a variety of wrist sizes due to its proportions and contoured lugs, and its value, especially when found under $400. Some owners highlight its refined finishing and unique, non-homage design, while others appreciate its ruggedness and durability, with one noting PVD coating remained flawless after three years of heavy use. Accuracy figures range from excellent, with one owner reporting only 2 seconds lost per day, to inconsistent power reserve and occasional reported issues with the movement and stem. The lume is described as subpar by some, though one owner found it marginally better than a Seiko SKX007. Reservations are occasionally raised regarding warranty service and the use of folded end links on the bracelet.

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.
