Sinn U1

Tegimented Submarine steel 44mm case, 1000m of water resistance, highly legible dial and hands, Silicone strap with folding clasp and powered by an automatic SW200-1 movement. The Sinn U1 has proper tool watch credentials, and is as tough as they come.

This particular piece was first sold in 2010 and presents in TZ good condition. Case generally very little in the way of scratches due to the tegimented steel, but has been graded as 'good' due to the presence of a ding on the inside top of the upper left lug, on the outer edge of the upper right lug, and some small nicks on the lower right lug. Case back shows some mild scratching. Please see images for full condition details.

Silicone strap has been cut to suit a roughly 7in wrist. Clasp is very clean with only light marks.

No known service history. Currently keeping COSC time.

Comes with outer box, inner box (show wear), instruction manual, warranty card dated 2010 and Watch Vault cleaning cloth.

One of the great tool watches.
