Sinn 103 St Sa E Watch Hands-On

Sinn 103 St Sa E Watch Hands-On

Sinn is known for making dependable, well-assembled apparatus watches ordinarily at an affordable price point. The latest watch in the 103 chronograph line, the Sinn 103 St Sa E is no exception. With a chronograph, bi-directional commencement bezel, day-date marker, and crown-monitors, this is a watch worked to be a utilitarian and trustworthy every day wearer in the gathering I’d call ‘vintage-inspired pilot chronographs.’ The 103 has been a staple of Sinn’s item lineup throughout recent years – in one structure or the other. This latest variation embraces its vintage roots with the use of fake patina lume on the markers and hands.

Collectors acquainted with chronograph movements will recognize that the Sinn 103 is powered by the Valjoux 7750. The biggest giveaway is of course, the dial, which has the three-dial format with sub-dials at 12:00, 6:00, and 9:00. Of all the modern chronograph movements still underway, I believe the Valjoux 7750 is the just one with this specific sub-dial design. This is an appropriate movement for an apparatus watch as it is programmed, time-tested, reliable, and natural to watchmakers and hence, easy to keep up and service. The Valjoux 7750 in the Sinn 103 is stun resistant, has against magnetic shielding, and provides 42 hours of power reserve.


With case dimensions of 41mm wide and 17mm thick, there’s no escaping that the Sinn 103 is a stout watch. However, considering the use of a presentation caseback in a 200m water resistant case alongside the domed sapphire crystal on the dial, it shouldn’t be excessively astonishing. Still, this watch is considerably thicker than numerous mechanical chronographs and you’d find tucking it under a sleeve pretty extreme. Proceeding onward, the case is machined from stainless steel and is polished all over. I believe the bezel is made from steel too and some collectors may locate this disappointing as more advanced materials like ceramic would’ve provided better longevity.

The crown and pushers are both screw down and large enough to be easy to use and not very fiddly. Despite its large size, the Sinn wears comfortably on the wrist. I don’t see it fitting in quite well with formal office wear however with jeans and a shirt or in the event that you happen to have a non-desk jumping position, the Sinn 103 should fit right in and not be excessively prominent. The watch is available on a rubber or leather strap, or Sinn’s determinedly fabricated H-interface bracelet. While I am personally an enthusiast of Sinn’s fine connection bracelet, I think the H-interface version is better suited here given the larger case size.

As a pilot’s watch, the dial on the Sinn 103 St Sa E is matte dark with contrasting text and indices to maximize legibility. The hour markers are Arabic and painted on the dial with the fake patina lume that is a signature to this variation. The syringe hands are likewise filled with the same lume and takes the vintage feel of the entire watch up an indent. The false patina keeps up the high contrast with the dial required for the legibility that pilot watches are known for.


The sub-dial at 12:00 indicates chronograph minutes, the one at 6:00 the chronograph hours, and the one at 9:00 is for persistent seconds. At 3:00, we have the day-date marker, which fortunately is dark with white text on it. This preserves legibility while helping it blend in well with the dial. A white with dark text version would look terrible, to lay it out simply. The date wheel in the watch we got our hands on was in German, which is quite common for Sinn. However, I do believe English date wheels are available, especially whenever purchased through their American distributor, WatchBuys.

I think the use of fake patina lume might be all in all too much for some collectors – however I personally burrow it. On the off chance that you do happen to be in the camp that would prefer it without, stress not, for Sinn has other variations of the Sinn 103. Quibbling over lume shading aside, it’s difficult to argue that this is a fine instrument observe indeed. The solitary two missing Sinn technologies are the tegimented steel and argon moistness marker for the water-sealing system, however those would add further cost to creation, not to mention the tegimented steel’s dull dim won’t suit this watch well.

To top everything off, The Sinn 103 St Sa E is manufactured in a limited run of 300 pieces, a number that I think really is exclusive unlike some of the 4-figure creation runs we’ve seen for the current year. The Sinn 103 St Sa E ships on leather for $2,250 and on the H-interface bracelet for $2,560. In the event that you would prefer one of the Sinn 103s without the fake vintage lume, the non-limited versions start from $1,880 – a decent value suggestion for a German apparatus watch that’s constructed like a tank.  sinn.de
