Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely appreciate the CWC Tamar for its historical significance and vintage aesthetic, with the Ronda quartz movement and fixed spring bars being considered acceptable. However, some owners feel the price is not justified for a basic quartz watch with average finishing and faux indices, with one noting a case polish mark and chip after a few months. The design elements referencing the Welsh flag, including colors and a dragon motif, suggest a specific target audience. On balance, owners value the CWC Tamar for its historical connection and unique design, though some question its value proposition at the price point.
Owners widely praise the Sheffield Diver 1 for its substantial, rugged case and overall quality at an affordable price, with many appreciating the blue dial and dial patina. Some owners note the bezel action could be crisper, and one found the non-quick-set date inconvenient. An owner reported difficulty removing the caseback during servicing, and another experienced tiny shock springs disappearing during cleaning. Overall, owners rate the Sheffield Diver 1 highly for its build quality and value.
