Bell & Ross BR-X1 Tourbillon Sapphire Chronograph

The Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH is noted for its modern, Transformer-like 45mm case with switch-style chronograph pushers and a skeletonized movement visible through a sapphire dial. Reviewers praise its superb and qualitative finishing and dial. However, the watch is criticized for its high price, with limited editions ranging from $163,000 to $238,000, and its movement relies on a Dubois-Depraz module over an ETA base, a point of consideration against competitors with in-house calibers. On balance, reviewers consider the Bell & Ross BR-X1 TOURBILLON SAPPHIRE CHRONOGRAPH a significant image-builder for the brand, with its main drawbacks being its high price and modular movement.

Massena LAB Angelus Chronographe Télémètre Massena LAB

Owners praise the Massena LAB Angelus Chronographe Télémètre Massena LAB for its lovely and subtle design, with a stepped bezel that can make the 37mm case appear thinner. Reviewers highlight the elegant case, vintage charm, and balanced dial, noting Geneva stripes on gold-finished bridges and hand-chamfered edges as part of its finishing. One owner considers the $5K price point expensive, citing the use of an off-the-shelf movement. The manual-wind A5000 caliber powers the watch, offering a 42-hour power reserve. On balance, owners and reviewers rate the Massena LAB Angelus Chronographe Télémètre Massena LAB highly for its elegant vintage-inspired design and refined finishing.
