Seiko Prospex Sea 1968 Heritage Diver's GMTvsVario Empire Tachymètre Chronograph

The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and comfortable wearability, offering good value for its price point. Owners and reviewers highlight the attractive silver/white sunray dial, blue ceramic bezel, and the premium feel of the improved bracelet clasp with excellent micro-adjustment. The Caliber 6R54 movement provides a 72-hour power reserve, and real-world accuracy often exceeds its stated range of +25 to -15 seconds per day, with some owners reporting figures around +3 to +5 seconds per day. However, the caller-style GMT functionality is a point of contention for some, who find the GMT scale difficult to read and prefer a flyer GMT at this price. Some also find the crown position at 4 o'clock undesirable, and a few note a lack of dial contrast or illegibility of the inner bezel.

The Vario Empire Tachymètre Chronograph is praised for its elegant, art deco-inspired multi-layered dial and comfortable leather strap. Owners note its 38mm diameter, 46mm lug-to-lug, and 11.5mm thickness, along with a sapphire crystal and 5 ATM water resistance. Criticisms include the use of different fonts for sub-dial and perimeter markers, and the absence of a traditional running second hand. Overall, owners appreciate the Vario Empire Tachymètre Chronograph for its distinctive dial design and comfortable wearability.
