Breitling Navitimer B01 Chronograph 41vsOmega Speedmaster Racing Co-Axial Chronograph 40 mm

The Breitling Navitimer B01 Chronograph 41 is praised for its iconic slide-rule bezel, in-house B01 movement with smooth operation, and appealing 41mm case size. Owners appreciate the updated features like the ergonomic crown, machined bracelet clasp, and available color options, with some specifically noting the blue dial's color-shifting properties and the date at 6 o'clock. However, concerns exist regarding its 30m water resistance, with some reporting fogging from light rain and avoiding significant water exposure. Criticisms also include a dislike for the crocodile leather strap and brushed case finish over polished, a domed crystal deemed too pronounced by some, and a lack of micro-adjustment on the bracelet clasp. One owner notes the watch runs fast and gains time, requiring local service.

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.
