Reviews

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

Studio Underd0g Watermel0n (Gen3)

The Studio Underd0g Watermel0n (Gen3) is widely praised for its novel, playful, and colorful design, often described as a fun, juicy, and fresh choice perfect for summer and as a conversation starter. Owners report outstanding build quality and a timeless design, with the strap also feeling premium. The manual-wind Seagull ST1901 movement is noted as mechanically interesting, with one owner reporting impressive accuracy of 1-3 seconds per day. However, one owner found the watermelon colorway became tiresome and felt the finishing was not very good, leading to a cheaper feel over time. The winding action is described as silent and smooth, though some find the lack of tactile feedback disconnects from the expected winding experience. Overall, owners and reviewers consider the Studio Underd0g Watermel0n (Gen3) a well-executed, irreverent, and fairly priced chronograph with a unique design.

Yema Rallygraf Meca-Quartz

The Yema Rallygraf Meca-Quartz is praised for its heritage reissue design, small and thin 39mm case, and good build quality for its price, with owners noting tactile pushers and a surprisingly good quality strap. Some owners report issues with dial rotation when chronograph pushers are depressed, crooked indices, or misaligned bezels, though one user suggests alignment issues are common for watches under $400. The VK64 meca-quartz movement is a point of contention; while it offers good value, some criticize the lack of a running seconds register and the 24-hour subdial functioning only as an AM/PM indicator. On balance, owners and reviewers appreciate the Yema Rallygraf Meca-Quartz for its attractive vintage styling and solid construction at its price point, despite some concerns about quality control and the functionality of the subdial.
