This is not breaking news as far as the SINN Forum is concerned but Lothar Schmidt, chartered engineer and owner of SINN Spezialuhren, celebrates a special anniversary this September: he has successfully managed the company for 25 years! Under his supervision, the brand has developed a well-earned reputation as a manufacturer of high-quality mechanical watches with a cohesive and thoughtful design aesthetic.

To say there is a strong fan base for SINN on Watchuseek would be an understatement. It’s one of the most fervent and active forums on the entire site. As an example of this, a thread to show off WUS members SINN tool watches was started in 2012, and it’s still going strong to this day with watch shots being added daily.

In another example, An open letter was written to Herr Schmidt on the Watchuseek SINN forum way back in 2007 by WUS member Timothy Patrick from Ontario, Canada. Here is but a small extract from that letter singing the praises of SINN’s U2 watch:

“Mr. Schmidt, I, by nature am a very skeptical person and this watch was just too good to be true. So, being the middle of winter by now, I took it out for a nice long walk in -31 celsius weather, as I am prone to do, and it handled the jaunt quite fine. Over the course of the winter, I ended up wearing it on the outside of my gloves while cleaning out the driveway in vicious storm after vicious storm. It never stopped, never fogged, never lost time. It looked like it was the real deal. I then tested it further to reassure myself that this watch would never let me down. I left it outside in -30’s temps for the entire night and then brought it in and immersed it immediately in super-hot water in my sink. Throughout the whole test, it never slowed, stopped or fogged. Absolutely unbelievable.”

When Lothar Schmidt acquired the Helmut Sinn GmbH on 1st September 1994 a new calculation of time began for the SINN brand. Herr Schmidt effectively re-established the company. His aim was to technologically and strategically reposition the company so as to prepare it for the future.

A mechanical engineer by training, prior to SINN, Herr Schmidt worked at IWC in Schaffhausen, Switzerland. He is an innovative engineer, particularly when it comes to case design.

Between 1990 and 1993, he was also in charge of the technical product development of the newly re-established A. Lange und Söhne GmbH, which was at the time a subsidiary of IWC.

With the acquisition of SINN, Lothar Schmidt had found for himself a good foundation on which to develop his own ideas for technical watches and to fulfill his desire for watchmaking independence.

During his tenure, he has expanded the range of models and added new touches making a SINN watch a perfect watch to be worn each and every day.

He first developed model 244 from pure titanium with Magnetic Field Protection and a freely oscillating suspended movement. He also laid the groundwork for the high-quality standards that all SINN watches now represent.

SINN Diving Watches

This applies to SINN dive watches made from German Submarine Steel, which was tested and certified by Germanischer Lloyd in Hamburg (now DNV GL) in 2005 with a focus on pressure resistance and in accordance with the European EN205 diving device standard and the EN14143 standard. SINN was the first and only company in the industry to do so.

SINN Frankfurt Financial District Watch

The Frankfurt Financial District Watches, dress watches which display up to three times zone at a glance, was developed by Lothar Schmidt in 1999 as an homage to the city in which his company is based.

Today SINN has established itself as a high-quality watch brand and is well equipped for the challenges of the future. When Lothar Schmidt took over the company in 1994, it was still based in “Im Füldchen in Frankfurt-Rödelheim”. There were a dozen employees working at the company.

As the brand celebrates 25 years under Herr Schmidt’s leadership, there are over 120 employees working at SINN headquarters in Frankfurt-Sossenheim, to where the brand moved in September 2017. There are also around 45 employees at the affiliated companies SUG Glashütte (Sächsische Uhrentechnologie GmbH Glashütte) and S & S Uhrenmanufaktur GmbH.

Timothy Patrick concluded his letter by saying:

Thank you, Mr. Schmidt for making the U2. I feel like you made it specifically for me. I wish you all the best in your endeavors.

It’s clear a lot of Watchuseek members feel the same way.
