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.
Owners and reviewers widely praise the TAG Heuer Monaco Evergraph for its innovative TH80-00 automatic chronograph movement, which replaces traditional levers with flexible compliant mechanisms for enhanced durability and a consistently crisp tactile feel at the pushers. The 40mm titanium case is noted for its sportier, comfortable fit, and the transparent dial showcases the complex movement. However, opinions are divided on the watch's thickness and proportions, with some finding it too chunky and large for their wrists, while others feel it wears well and is a unique, top-tier TAG Heuer. The watch's design is also a point of contention, with some admiring its modern take on a classic historical design and others finding certain accents or the overall look unappealing. Overall, owners and reviewers rate the TAG Heuer Monaco Evergraph highly for its significant mechanical innovation and impressive execution of a modern chronograph.
The innovative TH-Carbonspring hairspring and the new Calibre TH-80 movement with its unique chronograph mechanism are highlighted as significant advancements. Reviewers noted the use of grade 5 titanium for a reduced weight.
