What people say

Owners + reviewers, side by side

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

Oblvlo IM Tourbillon

Owners widely praise the Oblvlo IM Tourbillon for its skeletonized dial and carbon fiber case finishing, noting it looks more expensive than its price. However, some owners find the minute markers difficult to read, impacting time setting, and accuracy averages around -10 seconds per day. Concerns also exist regarding long-term reliability and parts availability for Chinese tourbillons. On balance, owners rate the Oblvlo IM Tourbillon highly for its visually striking aesthetic and perceived value, despite practical readability and accuracy drawbacks.

Longines MASTER COLLECTION

The Longines Master Collection is widely praised for its excellent fit and finish, heritage-inspired design with engraved Breguet numerals, and dial textures, offering tremendous value. Owners appreciate its dressy, thin profile and the use of ETA movements, with specific models featuring triple-date, annual calendar, or moonphase chronograph complications. Some reviewers note the subdial cutting off the "7" on the Small Seconds model, the lack of micro-adjustments on the bracelet for a perfect fit, and a somewhat homogenous case finishing. The 30m water resistance on the Annual Calendar is considered light, and the traditional styling is not as popular as sport watches. The Master Collection Chronograph is lauded for its classic, vintage styling. Overall, owners rate the Longines Master Collection highly for its value and classic dress watch aesthetics.

From video reviewers
