It has a chrome front to the case, with a stainless-steel back. It has a 15 jewel Swiss lever movement, which is tonneau shaped. It has chatons around the jewels and has an early form of shock proofing.
 
The dial is simple and well executed, with tonneau shaped rail track minute markers, with a matching tonneau shaped sub second register at 6 O’clock. It has beautiful Bauhaus stylised numerals which is simplistic, but eye-catching. They exaggerate to fit the dial. It is signed shock absorbing, Swiss Made, to the dial.
 
The case has a chrome plated front and Stainless-Steel front. It measures 22mm x 29.5mm, with a lug-to-lug measurement of 37mm.

To the right is the chrome plated crown, which is original and functions well.
The case back is Stainless Steel, signed with the reference 2981 and the serial number 4000851. It has a well-executed brushed finish which matches the sides.
