Sinn 1736 St I 4NvsSerica Ref. 5330 Diving Chronometer Date

Owners widely praise the Sinn 1736 St I 4N for its elegant silver and gold combination, minimalistic design, and smooth winding action. The watch is noted for its versatility, suitable for both dress and casual wear, with a 100m water resistance rating. Accuracy is reported as excellent, with one owner observing no time deviation over six weeks. Some owners miss a second hand and find the stock strap uncomfortable, while others note the 36mm size can wear larger than expected due to its flat profile. The community is split on the price, with some hesitant to purchase without trying it on first. Overall, owners rate the Sinn 1736 St I 4N highly for its sophisticated design and reliable timekeeping at the price.

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.
