What people say

Owners + reviewers, side by side

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

Breitling Top Time B01 Racing

The Breitling Top Time B01 Racing is lauded for its compact 38mm cushion case, which enhances wearability and evokes 1960s designs, and its dashboard-inspired dials. Owners appreciate the in-house B01 automatic movement and the 100m water resistance. Some reviewers note the case features abundant polishing, with a minority desiring more brushed finishing. The perforated leather straps are designed to match the dial colors. Owners are split on the lug-to-lug length, with recommendations for in-person try-ons due to wrist shape variations. Overall, owners rate the Breitling Top Time B01 Racing highly for its compact, wearable design and the quality of its in-house movement.

TAG Heuer Connected Calibre E5

Owners widely criticize the TAG Heuer Connected Calibre E5 for its high price, with some finding its components and assembly not justified by the $2000 cost. Several owners report significant issues with battery drain, with Wear OS identified as a primary culprit, and some experience frequent bugs and software update problems, leading to regret over their purchase. One owner noted the lume on the mechanical module lasts only about five minutes. On balance, owners rate the TAG Heuer Connected Calibre E5 poorly due to its high price and reliability concerns.
