An extraordinary pilot watch

For our Series 31E we use a fully satinized i.e. by hand fine matt grounded stainless steel case with 42 mm diameter and 11.95 mm height and recase the HS81 manual wound movement in it. This watch is powered by the finely decorated hand winding Unitas pocket watch movement which is modified to an indirect center second and a special feature, which is visible only for the view of the wearer - the seconds zeroing.

To precisely set the time of a wrist watch most movements are equipped with a second stop – when the crown is wound, the second hand doesn’t move. The seconds zeroing is a much rarer design. When the crown is wound, the second hand continues to run until it reaches “60” and then it automatically stops – thus it is possible to use a time signal to set the watch to the second. 

Contemporary our model 31E is pressure-resistant up to 10 bar and equipped with sapphire glasses on front and back side. The watch wears a deep black contrast dial and handmade hour and minute hands. Like all the hour indices and the marking triangle, these steel pointers made in Saxony are coated with white luminescent material.

For the love of details

Also this watch was developed and built entirely in Germany - that is, Case, dial, hands, bracelet and clasp are all produced in Germany. The pocket watch movement we use is decorated, modified and regulated in our workshop in 5 positions. For this reason we engrave “Frankfurt” on the watch back.
