Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Elliot Brown HOLTON AUTOMATIC: 101-A10

The Elliot Brown HOLTON AUTOMATIC: 101-A10 is noted as an issued watch for UKSF, bearing a crow's foot and NSN marking. One owner reports the dial lume is lackluster, potentially due to the vintage aesthetic influencing the choice of Super-LumiNova. Overall, owners rate the Elliot Brown HOLTON AUTOMATIC: 101-A10 for its military provenance and issued status.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised as an excellent value gateway watch, with owners and reviewers highlighting its solid build and powerful lume. The 22mm bracelet is noted for its comfort, and the watch offers numerous style options. Some owners find the original SKX models heavy and bulky, while others appreciate their ruggedness and iconic dive watch design. The Seiko 5 Sports SKX series offers an upgraded movement with hacking and hand-winding, and standard spring bars for easier strap changes. However, it lacks the screw-down crown and ISO certification of the original SKX, leading some to consider it less of a tool watch. On balance, owners and reviewers rate the Seiko 5 Sports SKX series highly for its value and modern features, despite some preferring the tool watch capabilities of its predecessor.
