Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Yema Flygraf Bi-Compax French Air Force is praised for its attractive, toolish aesthetic and excellent quality for its price, featuring a legible Type A dial and a date complication. However, the mecha-quartz movement's chrono timer sweeps rather than ticks, and the acrylic crystal scratches easily. The 40mm titanium case is lightweight and satin-matte, but titanium scratches more easily than steel, and the oversized crown's purpose is questioned. Accuracy is noted at +/- 10 seconds per day, with a 42-hour power reserve. Overall, owners rate the Yema Flygraf Bi-Compax French Air Force positively for its value and tool-like design, despite concerns about material durability and past customer service issues.
The Yema Yachtingraff Seconde/Seconde/ is widely praised for its unique, artistic design, featuring a graffiti-style dial with hand-painted sub-dials and spray can-shaped pushers. Owners appreciate its 38.5mm case size, described as slim and compact for comfortable daily wear, with one forum member noting the bracelet as a standout feature. The watch is powered by a Seiko VK63 meca-quartz movement and is priced at €449. While its aesthetic is a strong draw, one owner flagged its higher price and reported poor customer support as drawbacks. On balance, owners and reviewers rate the Yema Yachtingraff Seconde/Seconde/ highly for its distinctive artistic dial and comfortable wearability at its price point.
