Bremont Terra Nova 42.5 ChronographvsOmega Speedmaster Racing Co-Axial Chronograph 40 mm

Owners report the DLC coating on the Bremont Terra Nova 42.5 Chronograph is durable, though one noted a ding on the barrel. The chronograph hand resets slightly off-center for one owner. Reviewers describe the 42.5mm case as blocky with satin finishing and minimal polishing, noting its 48.8mm lug-to-lug and 14.8mm thickness felt bulky on leather but improved with elastic or rubber straps. The winding action is satisfying, and the chronograph pushers are crisp, though the start/stop pusher requires significant force. The Cupro-Aluminium case is expected to patina over time, and the watch features a bi-directional bronze compass bezel with a black ceramic insert and a green gradient dial with full-block Super-LumiNova numerals. The rear sapphire caseback on a prototype was too dark to appreciate the movement, and text around a tourbillon window detracted from the dial.

Owners widely consider the 40mm case size of the Omega Speedmaster Racing Co-Axial Chronograph 40 mm ideal, distinguishing it from larger Speedmaster models. The Omega 3330 movement is seen as solid and serviceable due to its ETA origins, offering excellent value. However, some owners find the watch thicker than comparable automatic watches, with one noting a stiff second stopwatch button. Disagreements exist regarding its value, with one owner calling it Omega's greatest value while another found its thickness combined with the 40mm diameter a reason to move on. One owner reported misalignment at several hour markers and the '5' on the dial being too close to a subdial, while another noted subdials overlapping indices and touching the chapter ring. On balance, owners rate the Omega Speedmaster Racing Co-Axial Chronograph 40 mm highly for its 40mm case size and the value offered by the 3330 movement.
