Bremont Supermarine 500MvsLongines HYDROCONQUEST

Owners widely praise the Bremont Supermarine 500M's luxurious appearance and sapphire bezel, with some preferring its design over other luxury dive watches. Reviewers note its updated, legible dial with excellent, long-lasting Super-LumiNova lume. The hardened steel case with anti-reflective coating offers scratch resistance, and the crown placement is a favored feature. Some owners find the 43mm thickness substantial, and one reviewer questions the long-term water resistance of its three-piece case construction compared to traditional designs. Criticisms include the lack of a dive suit extension on the bracelet and a second hand that can be difficult to see in low light, with some finding the bezel markings could be more prominent. Overall, owners and reviewers consider the Bremont Supermarine 500M a handsome, rugged dive watch with a refined look that competes well with more expensive brands.

Owners widely praise the Longines HydroConquest's dial and finishing, with one owner finding it superior to a Rolex Submariner. The movement is noted as well-regulated, losing about 2 seconds per day. The watch is considered a versatile everyday or business-casual option, offering good value. However, owners criticize the bracelet for lacking tool-less micro-adjustment and describe winding the crown as a nuisance. Some in the line report tiny GMT markers that are difficult to read and the absence of a quick date adjust feature. Overall, owners rate the Longines HydroConquest highly for its finishing and value.
