The latest version of the Sinn 103 St Sa Replica – which Sinn has been offering in some form or another for as long as I can remember – is the first to completely assume the connection with these vintage models, thanks to the introduction of creamy luminescent material that mimics the aging found on vintage models. You'll find it here on both the hour markers and the syringe hands.

Don’t be fooled by faux-patina though, this is a contemporary replica watch, with much better water, pressure, and magnetic resistance than those made in the 1950s (but without the decades of wear and the additional character that comes with that experience). The replica watch comes in a polished stainless steel case that measures 41mm from side to side, and 47mm from lug to lug, and it sits high above the wrist, being 17mm thick with the domed crystal. That last number might be a problem for some, but the replica watch does wear rather well for something this thick. The sides of the lugs are brushed, and the lugs themselves slope downwards for a better fit on the wrist.

As mentioned above, the Best Replica Watch is powered by a Valjoux 7750, one of the more widely used self-winding chronograph movements, known for its reliability and serviceability. Sinn has made a few cosmetic changes to the base movement, such as adding its name on the rotor, but these are minor and have very little impact on the mechanism. The movement still carries the 42-hour power reserve, the day and date indicators, and the sturdy automatic winding mechanism.

The Sinn 103 St Sa is a limited edition of 300 pieces, and according to Sinn, exactly half were pre-sold to customers during the first 48 hours after it was unveiled. The replica watch is sold on three separate strap options. Prices start at $2,250 on the leather strap and go up to $2,560 on the fine link bracelet. There is a non-limited edition available from $1,880 as well, without the overt vintage references.
