What people say

Owners + reviewers, side by side

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

Glycine Airman No. 1 GMT

Owners widely praise the Glycine Airman No. 1 GMT for its historical significance and attractive dial. However, some find the 36mm case size to be a bit small, and the GMT hand can be difficult to distinguish from the minute hand. The watch has a very limited 3ATM water resistance. Later versions feature sapphire crystals, differing from earlier plexi models. Overall, owners value the Glycine Airman No. 1 GMT for its historical appeal and dial design, despite minor legibility and sizing concerns.

From video reviewers

The case finishing and dial colors are praised. The value proposition is tied to a sale price, with questions about long-term competitiveness.

Phoibos Reef Master

Owners widely praise the Phoibos Reef Master for its exceptional value, highlighting its sapphire crystal, DLC coating, and extensive BGW9 lume. The watch is noted for its cool lume, with one owner finding it not bulky despite its robust build. The Shamrock Green dial and texture are highly praised, as is the comfortable bracelet with solid end links. However, the bezel action is described as rough, and the basic folding clasp is a disappointment. Accuracy is reported as excellent, with one owner seeing +-2 sec/day. Some find the 42mm size almost too big for their wrists, and the date window is considered too small. Overall, owners rate the Phoibos Reef Master highly for its impressive feature set and value at its price point.
