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.
Owners praise the Fortis Marinemaster M-44 for its gorgeous appearance, significant wrist presence, and "crazy lume." Reviewers highlight its excellent build quality, COSC-certified movement accuracy of 0 seconds per day, and surprisingly comfortable 44mm case despite its 14.4mm thickness.
