Reviews

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

CWC (Cabot Watch Company) RN81 Diver Automatic Watch

Owners widely praise the CWC (Cabot Watch Company) RN81 Diver Automatic Watch for its robust build and preferred dial layout, featuring an iconic big triangle and sword hands reminiscent of the 1980 original. The bezel action is described as nice and chunky, and the case wears beautifully. Some reviewers note the polished case sides and "faux patina" lume color as unusual or slightly glossy for a military-issued watch, and fixed springbars are flagged as a potential drawback. Accuracy varies, with one owner reporting it running 3 seconds fast per 24 hours. On balance, owners and reviewers appreciate the CWC (Cabot Watch Company) RN81 Diver Automatic Watch for its faithful homage design and solid construction, despite some reservations about its finishing and price point.

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its thinness, with various sources citing measurements between 10.4mm and 10.8mm, and its comfortable wearability due to contoured lugs that make it feel smaller than its 39mm case size. Reviewers and owners consistently highlight its value, with some considering it the best dive watch under $400 and noting its refined finishing and smooth winding action. However, opinions are mixed on its design, with some finding it unique and others plain or questioning its homage status. Lume quality is a point of contention, with some finding it subpar and hard to read at night, while others describe it as marginally better than a Seiko SKX007. Some owners have also reported inconsistent power reserve or stem issues. Overall, owners and reviewers rate the Glycine Combat Sub Sport highly for its exceptional thinness and value proposition at the price point.
