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

Owners and reviewers widely praise the Longines Master Collection for its excellent fit and finish, heritage-inspired design with features like Breguet numerals and leaf hands, and the value it offers, particularly for complications like chronographs and annual calendars. Specific models are noted for their beautiful dial execution, creamy white barleycorn or blue starburst finishes, and practical complications. Some owners find the Master Collection thin and dressy, appreciating its vintage aesthetic. However, drawbacks mentioned include a subdial potentially obscuring numerals, a bracelet lacking micro-adjustments causing fit issues for some, and a case finishing described as homogenous by one owner. The 30m water resistance on annual calendar models is considered light, and the crown and pushers on the moon phase chronograph are described as uninspiring. One owner reported a broken moon phase setting mechanism.

From video reviewers

The diamond hour markers are a notable strength. The movement accuracy was not discussed.
