PARTNER TO THE WATCH INDUSTRY FOR OVER 100 YEARS

It was the pioneer Samuel Laubscher’s vision to produce the perfect watch screw for the watch industry. In the 19th century, Laubscher developed a lathe which made it possible for the first time to manufacture a watch screw completely in one operation – a milestone! Since then Laubscher has developed significantly. What has remained is its close cooperation with the prestigious Swiss watch industry – there are over 100 years of partnerships with numerous customers.

Watch screws and other watch parts are often so small that they are hardly visible to the naked eye. Watch screws play an important role in ensuring that a movement can display the famous Swiss punctuality and run accurately for decades. Industry experts claim that Laubscher is the best in the field of watch screws. Of course we like to hear that. In any case, we have over a century of experience and cover the entire production process in-house.

WATCH SCREWS – A CORE COMPETENCY FOR LAUBSCHER

Laubscher covers the entire process chain for the in-house production of watch screws. Highest quality is thus multiplied. Process reliability is our top priority and ensures that every single one of the tens of millions of screws we are allowed to produce each year is precisely processed and durable. Over the years we have continuously expanded the range of parts and developed it further together with our customers.
