Reviews

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

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.

Marnaut Safe Harbour 100

Owners widely praise the Marnaut Safe Harbour 100 for its value at EUR 549, noting the 2-year warranty and Italian leather strap. Reviewers highlight its divisive but fresh sea urchin-inspired dial and 39mm GADA-friendly case size, though one reviewer found the handset could get lost on the busy dial. The tonneau case, despite a 13.2mm thickness, wears well due to its curved mid-case and domed sapphire crystal. On balance, owners and reviewers rate the Marnaut Safe Harbour 100 highly for its unique design and strong value proposition within the microbrand segment.
