Sinn 140 St SvsSinn 936 S

The Sinn 140 St S is praised for its functional tool watch design and space-flight heritage, incorporating a central chronograph minute hand and Ar-Dehumidifying Technology. Owners note the Tegimented hardened case and bracelet offer durability, with one reporting excellent condition despite minor marks. The 44mm size is considered wearable, though the SZ01 movement, based on the ETA 7750, has a rotor wobble that may not appeal to all. Overall, owners and reviewers value the Sinn 140 St S for its robust build and historical connection.

The Sinn 936 S is lauded for its purposeful bicompax dial, scratch-resistant TEGIMENT-hardened black-coated case, and the in-house SZ05 movement. Reviewers highlight its 60-minute register for immediate readability and 100 meters of water resistance with pushers operable underwater, along with 1,000 gauss anti-magnetism. At 43mm and 15mm thick, its size is noted as large, and the price is €4,150. One reviewer expressed a desire for a re-engineered bracelet from Sinn, considering it a brand weakness. Overall, reviewers rate the Sinn 936 S highly for its focused chronograph purpose and robust specifications at its price point.
