Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Specht & Sohne SP0020 Egg Form Automatic 38mm NH34 GMT as an excellent value, noting the brand successfully executes many aspects of this homage. One owner reports the watch loses approximately 15 seconds per day, while the rose gold finish has shown no wear after nine months of ownership, and the rotor is not excessively noisy. Overall, owners rate the Specht & Sohne SP0020 Egg Form Automatic 38mm NH34 GMT highly for its impressive build quality and finishing at its price point.
The Seiko 5 Sports Field series is praised for its accessible explorer watch design and decent fit and finish for its price point. Reviewers note the inclusion of a caller GMT complication powered by the 4R34 automatic movement. On balance, owners and reviewers find the Seiko 5 Sports Field series a compelling option for its explorer aesthetic and GMT functionality at an accessible price.
The prominent five-sided GMT hand enhances legibility and adds a sophisticated aesthetic to the watch. The Seiko 5 Sports Field series offers similar functionality to the Explorer 2 at a lower price, making it a valuable option. Reviewers disagree on whether it's a missed opportunity for Seiko to release this model first, with one reviewer implying it would have been a more logical addition to their lineup.
