What people say

Owners + reviewers, side by side

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

Serica Ref. 5303 Diving Chronometer

Owners widely praise the Serica Ref. 5303 Diving Chronometer for its excellent wearability, definitive style, and smooth, confident bezel action. The dual scale on the bezel is noted as surprisingly useful, and the crown action, winding, and hacking are reported to work perfectly. One owner describes the Serica 5303-3 as gorgeous and unique, though another notes the crown can appear comically large. On balance, owners rate the Serica Ref. 5303 Diving Chronometer highly for its blend of unique design and robust functionality.

Tissot Heritage 1973

The Tissot Heritage 1973 is widely praised for its faithful vintage aesthetic, featuring a tonneau or cushion case with contrasting finishes and a panda dial with orange accents. Owners and reviewers alike appreciate its compelling remake of a 1970s racing watch, with some specifically noting the attractive dial and case curves. The watch is powered by the ETA 7753 automatic chronograph movement, offering a 60-hour power reserve. However, some find its 43mm or 44mm diameter to be large-wearing, and one owner reported difficulty setting the date and a chronograph reset that is consistently one second off. Accuracy figures vary, with one owner noting 10-15 seconds per day. The radial brushed case finish, while visually appealing, is noted as being prone to scratches that are difficult to polish out. Overall, owners and reviewers rate the Tissot Heritage 1973 highly for its tempting value and credible vintage racing style.
