Beaufort BicompaxvsOmega Speedmaster Racing Co-Axial Chronograph 40 mm

Owners widely praise the Beaufort Bicompax for its attractive bicompax chronograph design, clean aesthetic, and excellent legibility with effective lume. The Sellita SW510 BH b movement is noted for performing well, with winding and setting actions comparable to ETA movements and accuracy within COSC parameters at +5 seconds/day. Fit and finish are considered spot on, with a well-executed gradient dial and subdials, and the h-link bracelet is described as comfortable and easy to size. Some owners find the price a bit high for the specifications on paper, and one commenter felt the blue dial could have more depth. On balance, owners and reviewers rate the Beaufort Bicompax highly for its vintage aesthetic and reliable manual-wind chronograph movement at 40.5mm.

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.
