Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely report the Edox Grand Ocean Chronograph is a reliable and accurate quartz watch that has proven durable over years of ownership. Some reviewers note the 43mm case wears larger than expected due to its thickness, though curved lugs and a fitted rubber strap offer some mitigation, albeit limiting strap options. Reviewers criticize the applied markers on the black PVD model for low contrast and reduced legibility, and the lume is described as scant and fading quickly. On balance, owners rate the Edox Grand Ocean Chronograph highly for its proven durability and accuracy as a quartz timepiece.
Owners appreciate Resco's customization options and the versatility of PVD cases on NATO, Zulu, or leather straps for the RESCO R-TAG DLC, with one owner noting the watches are tough and look the part. However, one owner reported their unit randomly stopped working, and a second unit experienced rusting issues. Another reviewer flagged roughness in the DLC coating, deeming it unacceptable for the price and comparing the case finishing to older, less expensive models. Overall, owners are split on the RESCO R-TAG DLC, with praise for its toughness and customization weighed against reports of functional failures and finishing concerns.
