Edox Neptunian Grande Réserve Date AutomaticvsSeiko Prospex Sea 1968 Heritage Diver's GMT

Owners widely praise the Edox Neptunian Grande Réserve Date Automatic for its robust build and refined design, with reviewers highlighting its 42mm case as versatile and wearable, aided by a 12.3mm thickness. The Caliber 808 automatic movement, based on the La Joux-Perret G100, provides a 68-hour power reserve and is noted for its accuracy, with one source reporting +/-12 seconds per day. Legibility is enhanced by Super-LumiNova X1. The watch is priced at EUR 1,890 and features a ceramic bezel and sapphire crystal. Some owners find the 42mm case size large, and one reviewer felt the emphasis on the 68-hour power reserve was slightly overstated compared to competitors. Overall, owners and reviewers rate the Edox Neptunian Grande Réserve Date Automatic highly for its refined dive watch aesthetics and practical wearability at its price point.

The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and value, with owners noting its comfortable wearability and attractive aesthetic, particularly the silver/white sunray dial and blue ceramic bezel. The improved bracelet clasp with excellent micro-adjustment is a recurring positive point. Some owners report accuracy figures of +3 seconds per day or +/- 5 seconds per day, exceeding the movement's stated range. However, the GMT functionality is considered secondary to its dive watch capabilities by some, with the GMT scale being difficult to read and the caller-style GMT movement being a drawback for certain users. The dial contrast is also noted as lacking by some, and the crown at 4 o'clock is undesirable for a few. On balance, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT highly for its blend of dive watch character and GMT functionality, offering significant features for its price.
