Timing nature

UTC Extreme

Versatile and suitable for all kinds of conditions, UTC Extreme is the obvious choice for both mountaineers and inner-city adventurers.

UTC stands for Universal Time Coordinated and compared to its role model the Royal Steel Chronograph, the Extreme comes with a wider dial that can display a second time zone. In addition, the see-through engraved case-back and the screwed bezel add to the industrial feeling of the timepiece.

Assembled by hand

All our timepieces are assembled by hand, one by one, at the Sjöö Sandström workshop in Stockholm. Since a watch consists of several hundred parts that must be tuned with exact precision, this is indeed a work for the perfectionists. Each Sjöö Sandström model is produced in small series and every timepiece is meticulously tested before release.

For adventurous persons

Boasting a diameter of 44.2 mm, this is handmade masculinity at its best.
