Divers style watches are very popular, and this Sicura Superwaterproof 400 is a fine example of why that is so.


This watch was launched in 1971, and in 1972 Sicura changed the design of their logo, so this watch had to be made in 1971.


This is a divers style watch rather than a proper divers watch.  A true divers watch would look similar, but have features like a unidirectional bezel (this one rotates either way without clicks) and a screw down crown.  But as we recommend never getting a vintage watch wet, the divers style ‘superwaterproof’ delivers a lot for the money.

Let’s also clear up the ‘Sicura by Breitling’ myth.  Breitling breifly closed down in 1979, and the owner of Sicura, a Mr Ernest Schneider, bought the brand.  There are no Sicura watches with Breitling movements to the best of our knowledge, and Mr Schneider decided to close Sicura and concentrate on Breitling, which proved to be a good decision.  But at the time this watch was made there was no relationship between Sicura and Breitling at all.  Do not believe the eBay sellers!

This example has been used, and you can see the evidence all over the watch.  However the acrylic crystal is new, as is the leather strap, and the hands have been re lumed.  The EB 8021 23 jewel movement is working well, so it is ready to wear.

This watch will be supplied with our Certificate of Authenticity.
