Formex Essence ThirtyNinevsSugess Tourbillon Master SU8004

The Formex Essence ThirtyNine is praised for its impressive build quality and value, featuring a patented case suspension system for comfort and protection. It houses a COSC-certified Sellita SW200-1 movement with a 38-hour power reserve and a tool-free strap quick-release system. A minor inconvenience noted is the specific closing order of the clasp. On balance, reviewers rate the Formex Essence ThirtyNine highly for its comfortable wearability and excellent value at its price point.

Owners widely praise the Sugess Tourbillon Master SU8004 for its stunning enamel dial, incredible finishing for the price, and the visual appeal of its genuine tourbillon, with some reporting exceptional accuracy of +/- 1 second per day. The Seagull ST8230 movement is considered a reliable automatic tourbillon at an accessible price point, offering a complex complication that functions as intended, though it is not considered world-class compared to Swiss movements. Some owners find the strap and buckle comically large, the winding stem flimsy, and the crown small for winding, while others note the flat, reflective crystal and question long-term durability and serviceability due to its Chinese origin and limited local support. The Sugess Tourbillon Master SU8004 is considered a genuine option at a price comparable to replicas, valued for its aesthetic appeal and the presence of a tourbillon complication.
