Christopher Ward C60 Sapphire EdgevsSeiko Prospex Sea 1965 Heritage Diver's Watch

Owners widely praise the Christopher Ward C60 Sapphire Edge for its innovative deep blue sapphire dial, which is considered superior to other transparent dial executions, and its slim, ergonomic 42mm case. The lumed rubber strap is also a frequently highlighted feature, contributing to the watch's homogeneous luminosity and "damn cool" aesthetic. The watch is noted for offering incredible value, with a Sellita SW300-1 movement providing a 56-hour power reserve and 60ATM water resistance. However, one owner reported the sapphire dial cracked from the inside during regular use, and the brand denied warranty repair for this issue. Overall, owners and reviewers rate the Christopher Ward C60 Sapphire Edge highly for its striking dial execution and innovative features at its price point.

The Seiko Prospex Sea 1965 Heritage Diver's Watch is praised for its refined engineering and updated features, including a 300m water resistance and a 72-hour power reserve from the Caliber 6R55 movement in a 40mm case. Owners note its better build quality and interesting finishing with a mix of polished and brushed surfaces. The "Tranquil Teal" variant features a jewel-toned dial with a rippling-water pattern. However, some owners consider the price too high, and concerns exist regarding the accuracy of the 6R movements, with some reporting theirs run slow. One review notes a reflective dial that impacts legibility. On balance, owners and reviewers appreciate the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined design and improved specifications over previous generations, despite some reservations about movement accuracy and price.
