SIC1 Sicura Worldtimer Diving. Watch measures an exceptionally large 38mm (for that time) and is made from steel. Manual winding movement with 21 jewels. Plastic crystal on the front and a closed case back. Water resistant. Functions are hours, minutes, sweep seconds and a rotating worldtime bezel. This watch is vintage and comes without a strap and could benefit from a cleaning/service hence the price. Great and very rare model from the sixties especially in this 38mm case!
