What people say

Owners + reviewers, side by side

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

Breitling Navitimer B02 Chronograph 41 Cosmonaute

Owners widely praise the Breitling Navitimer B02 Chronograph 41 Cosmonaute for its striking 24-hour dial, historical significance, and overall craftsmanship, with some calling it the best-looking Navitimer. The manual-wind B02 movement, hand-wound and engraved with mission details in some variants, contributes to a comfortable 41mm case size and 13mm thickness. Reviewers note the 24-hour display was "extremely helpful" for tracking mission elapsed time, and specific limited editions feature unique elements like blue meteorite dials or platinum bezels. However, some owners find the 24-hour dial busy and difficult to read at a glance, and one owner reported a chipped lume on the minute hand requiring service. Overall, owners and reviewers rate the Breitling Navitimer B02 Chronograph 41 Cosmonaute highly for its unique aesthetic and historical connection to space travel.

From video reviewers

The hand-wound Manufacture Caliber B02 delivers impressive 70-hour power reserve and precise timekeeping in a limited 450-piece release. The 24-hour dial effectively honors the Cosmonaute's space heritage while the platinum bezel adds distinctive design character. However, 30-meter water resistance and a non-screw-down crown are significant limitations at the $11,900 price point.

Lorca MODEL No.2 CHRONOGRAPH

The Lorca MODEL No.2 CHRONOGRAPH is praised for its well-made construction and vintage-inspired aesthetic, featuring a 37mm case, a balanced three-register dial, and a quality bracelet and clasp suitable for daily wear. It includes a manual-wind Sellita SW510M movement with a 63-hour power reserve and offers 100 meters of water resistance in a thin package. Reviewers note a unique grooved bi-directional bezel, which is described as an atypical but potentially divisive choice for a chronograph. On balance, reviewers find the Lorca MODEL No.2 CHRONOGRAPH to be a well-made watch that successfully blends vintage charm with contemporary design.

From video reviewers

The Lorca Model No.2 Chronograph features a notable guilloché bezel that adds vintage flair to its design. The watch is powered by a Swiss Sellita SW510M manual movement, offering 63 hours of power reserve. A potential drawback is the relatively small 37mm size.
