For numerous years the Sinn 142.St has been a significant part in Sinn’s proficient chronograph arrangement. Sadly, the finish of the Lemania 5100 type in 2002 at first brought about this striking model’s shade call.

Sinn 142.St – reference 142.010

My first experience with Sinn was in the mid nineties. Helmut Sinn was still in charge. Sinn was for all intents and purposes obscure outside of Germany. Your best possibility? Conversing with a pilot who might have perceived the name from a portion of their plane instruments. Thusly, the main part of Helmut’s client base were pilots. This was a comfortable relationship for Helmut, who was a previous pilot himself. Be that as it may, when one procures a standing for greatness in a specialty field, the majority make certain to discover at some point or another. It wasn’t well before watch enthusiasts found this shrouded mystery, and rushed to the German brand. I was one of them.

I still love it

The first Sinn I purchased was a Sinn 142.St. I cherished the plan and I adored the Lemania 5100 usefulness and design. I still love it. Around then Sinn offered their model 142.St in two case completes, combined cleaned and brushed (ref. 142.010), and tangle shot blasted (142.020). The first one, similar to the one in this 52Mondayz scene, had and has my inclination. Different varieties were accessible also. Like a dark PVD covered rendition and a variant coming up short on the 24-hour sign named 140.

Not the first programmed chronograph in space

The Sinn 140/142 became acclaimed in light of the fact that it had been utilized by astronauts. The Sinn 140 was believed to be the first programmed chronograph in Space when German astronaut Reinhard Furrer wore it during the Spacelab D1 mission in 1985. In 2007, nonetheless, that changed. It was then established that US Air Force Col. William Pogue wore a programmed Seiko 6139-6002 chronograph during the NASA Skylab 4 mission which occurred in 1973. Our Michael Stockton did an instructive review on this event and watch, which you’ll have the option to discover here .

Pros and cons of the 5100

By 1997 Lemania had plans to stop their type 5100. The simplistic plan of the 5100 not, at this point fitted their product offering and reasoning. Likewise, the apparatuses for the movement were obsolete and needing restoration. The necessary investment couldn’t be justified by the type’s restricted deals to its three remaining main customers: Fortis, Sinn, and Tutima. At first, these leftover customers concurred on a substantial cost increment to save the development. It almost multiplied from CHF 230 to CHF 400. It endure five additional years. That slight stay of execution empowered Fortis, Sinn, and Tutima to discover choices. By 2002 the Lemania 5100 was formally removed from creation. The finish of an era.

The pros

The Lemania 5100, because of its construction, is a chronograph development that can withstand enormous stuns without its chronograph seconds hand stopping. Most chronographs utilize a halfway wheel. This isn’t the situation in the Lemania 5100. Instead, the 5100 chronograph work is straightforwardly determined. The type withstands increasing speed in abundance of 7G without loss of exactness. Its roughness is unbelievable. The type additionally keeps up its exactness over significant stretches without overhauling. Administration stretches from four to seven years have demonstrated to be sufficient.

The cons

On the other hand, the 5100’s was not without its shortcomings. It has a basic, good old construction. Like an old pocket watch or a mechanical morning timer, it utilizes a column construction. And afterward there’s the utilization of some nylon parts in the development. Nylon components were viewed as cost-compelling and reformist in 1978. Obviously, there are not many that would shield the proceeded with utilization of nylon components these days.

By the time ’97 moved around, the inclination had changed. Outwardly of the development, two more nylon parts are utilized. Dark nylon half-moons that help the rotor and retain stuns from the rotor if there should be an occurrence of hard blows. This nylon ring around the development fills another need too; it conceals a significant part of the column construction from the normal watcher 😉

I acquired the above image of the Lemania 5100 development from in Offenbach am Main, Germany. It is elusive dependable after-deals for the 5100. On the off chance that you’re situated in Europe this company may merit a try.

What happened to my first 142.St?

Did you notice? The bird peered toward among you may have spotted it… The imagined 142.St can’t in any way, shape or form be the first model I claimed. We’ll get to what exactly makes this model distinct from the first toward the finish of the article. Yet, what befell my first piece? All things considered, I gave it to a companion of mine who still wears it from tim-to-time. I lamented allowing it to fly the nest almost when it left. However, getting my hands on another one? That wouldn’t be easy…

Thankfully, I had a decent connection with Sinn and had become their representative for The Netherlands. It was a job that gave me much joy for more than 20 years. Act of kindness some help, Sinn offered to deliver a 142.010 particularly for me from an extra case which they had in stock. Obviously, I cheerfully acknowledged it, and it turned into a processing plant created one-off.

The 142.010 in its unique Sinn box

Why a unique case? The Sinn 142.010 — with cleaned and brushed case — was suspended around 1997. Those models were provided with tritium dial and hands as it were. When the model highlighted in this article was created, all Sinn watches, including the 142.020, had Luminova dials.

And so my watch wound up as the lone authority industrial facility delivered Sinn 142.St ref. 142.010 with a Luminova dial. I saw also that the tritium dials had ‘Automatic’ written in English in the dial, while the later Luminova dials got “Automatik” in German. The last more in accordance with the German day sign which Sinn utilized in their Lemania 5100 developments as well.

Sinn 142 today

After the “old” 142s dried out in the mid 2000s, it took Sinn a couple of years to come up with another option. The new SZ01 chronograph development in the end carried this job. In light of the trusted Valjoux 7750, the SZ01 sports the Lemania 5100 principle fascination — a focal second and moment chronograph hand. It doesn’t offer the little 24-hour counter at 12 o’clock, be that as it may, and therefor takes after the Sinn 140 more than the 142.

The case back of the current Sinn 140.St

Easy to understand why today just a 140 model can be found in the . You’ll discover Robert-Jan’s involved survey of the Sinn 140.St.S here.

You can locate a decent used Sinn 142.St with Lemania 5100 on Chrono24 for around €2,500. A new Sinn 140A will slow down you in any event €3,850. An idiosyncratic detail is that Sinn still today imprints “1st Automatic Chronograph in Space” for the situation back of their new 140 models. Become familiar with Sinn here.
