Serica Ref. 5330 Diving Chronometer DatevsDOXA SUB 600T

Serica is praised for its comfortable 39mm case, distinctive twin-scale bezel, and well-executed mesh bracelet. Owners widely report a dial balance and minimal text inspired by 60s dive watches. However, multiple owners flag significant quality control issues, including dials moving when the crown is pulled, minute hands jumping, and misaligned or difficult-to-turn bezels. The 5330 Dive Chronometer variant, which includes a date window, retails for €1,690 and uses a COSC-certified Soprod M100 automatic movement. Overall, owners rate Serica highly for its comfortable 39mm size and dive watch aesthetics, though quality control concerns are a notable caveat.

The DOXA SUB 600T is widely praised for its purposeful, angular, and unique 80s-inspired aesthetic, available in a variety of saturated dial colors and bezel options. Reviewers and owners highlight its tactile bezel action, grippy crown, and improved lume compared to previous models. However, multiple sources identify the excessively tall and blocky case back as a significant shortcoming, leading to a top-heavy feel and tendency to shift on the wrist, with some owners questioning its wearability on smaller wrists. The Sellita SW200-1 movement's 38-hour power reserve is also noted as underwhelming for the price point, and strap/clasp adjustments can be challenging for a comfortable fit. On balance, owners and reviewers appreciate the DOXA SUB 600T's distinctive tool watch character and vibrant colorways, despite the noted wearability and movement power reserve concerns.
