Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Glycine Combat Sub Sport for its exceptional value, often found under $400, its solid build with brushed finishing, and its notably thin case profile, with many sources citing dimensions around 10.4mm to 10.8mm, making it comfortable and wearable. Reviewers and owners consistently highlight its unique, non-homage aesthetic and excellent timekeeping, with some reporting accuracy within +1/+2 seconds per day, though one owner noted their Sellita SW200 movement ran at approximately +6 to +9 seconds per day. Some owners dislike the "COMBAT" text on the dial and find the lume sub-par, while others note inconsistent power reserve not always reaching the advertised 42 hours. On balance, owners and reviewers rate the Glycine Combat Sub Sport highly for its outstanding value and comfortable, thin wearability.
Owners recommend the March LA.B Belza Automatique for its design-forward, daring, and unusual timepiece aesthetic. The La Joux-Perret G100 automatic movement is noted as well-decorated. On balance, owners and reviewers rate the March LA.B Belza Automatique highly for its distinctive, '70s-inspired design.
