What exactly are "JS Unique Watches"?
Two main options:
-
JS Watch Co. Reykjavik (Iceland, since 2005)
- Official brand: JS Watch Co.
- Founders: Sigurdur Jonsson and Gilbert O. Gudjonsson
- Production: a few hundred watches per year
- Using Soprod, ETA or La Joux-Perret movements , completely hand-assembled
-
Each watch has an individual serial number (e.g. “No. 037”)
These can be dated via serial and work number.
-
JS (unique watches, e.g., from small German workshops)
- mostly custom-made (often with ETA 6498, Unitas Works)
- Not an official series, but individual pieces (the name "JS" here stands for the watchmaker)
- Dating is done here via the work used and the design.

Age determination in German “JS Unique Watches”
If your watch doesn't bear any reference to Reykjavik or Iceland, but instead "JS Unikatuhren Germany", the following applies:
Notes on the chronological allocation:
| feature | Period / Style |
|---|---|
| Hand engraving “JS Unikatuhren – Germany” / open Eta-Unitas 6498 | ca. 1995 – 2008 |
| Classic marine or deck watch design (geared edge, small seconds) | ca. 2000 – 2010 |
| Laser-engraved simple JS logo / no serial number | after 2010 |
| Engraving "Lörrach", "Pforzheim" or similar. | mostly small workshop-made pieces from the 2000s |
→ Mechanical core usually ETA 6498-1 or 6497-1 – these movements come from verifiable ETA production (serial numbers 36xxxxx – 39xxxxx = approx. 1998–2006).

Choose your favorite design - JS Unique Watches Individual Custom Watches
This is our first clock that holds your hands between the leaves. With the lower divider, the minute, second, and hour hands run beneath the dial. These are cut out in such a way that all hands are always clearly visible. The times are marked with a diamond on the clock face, a very intricate process in the handcrafted production of these Australian clocks.
The edge of the time disc is handcrafted and, depending on the version, rhodium-plated or coated in red, yellow, or black. The dial is either gold-plated or coated with a special transparent lacquer developed specifically for the watch.
This is also reflected in some of the timepieces available today. Wearing a single-handed watch demonstrates a confident approach to time, showing that one is not bothered by a single minute. The focus of these wristwatches lies in the elegant, individual, and precise technology of the built-in movement, which has been meticulously refined and redesigned.
Regardless of your personal taste, single-hand clocks are always a sure way to spark curiosity. In our wall clock gallery, you'll find both ready-made wall clocks and unique pieces we've created for our customers.
Only JS watches
Branch: Brand History: JS Unikatuhren, a small Swiss watchmaker based in Othmarsingen/Aargau, produces mechanically crafted, individually unique watches. Each watch is made entirely by hand, sometimes using techniques that are over 100 years old. Enamel work, profile finishing, artistic grinding, hand-printing, and hand-angled adjustments are just a small part of the manual work performed here, a skill mastered by only a few companies today.
The design of Elan wristwatches is timeless and allows for a wide variety of styles. They are powered exclusively by various Swiss automatic or manual-winding movements, which are refined and upgraded in our own workshop.
