Glycine Airman No. 1 GMTvsNivada Grenchen Antarctic 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.

The Nivada Grenchen Antarctic GMT is widely praised for its authentic retro charm and excellent 36mm case proportions, with reviewers highlighting its faithful 1970s revival design and warm aesthetic. The watch features a Super Compressor-style case, a boxed Plexiglass crystal, and a caller-style Soprod C125 GMT movement with a 42-hour power reserve. However, its 50-meter water resistance is considered acceptable but not robust for a sporty watch, and the GMT hand is noted as being short and difficult to read by some. The internal bezel's tactile feedback could be stronger, and the Plexiglass crystal scratches easily. On balance, reviewers find the Nivada Grenchen Antarctic GMT to be a compelling retro-vintage option for smaller-cased GMTs, particularly for its design and compact sizing at its price point.
