Designed by Roger Tallon, and fitted with the original NSA bracelet, this DS N1 is high quality.  Model reference 184.7000.41


This model was launched at Basel 1983, and we have adverts from that year too.  By 1986 the N2 had replaced the DS N1, so it was a condensed production run.


Roger Tallon was one of the twentieth century’s leading industrial designers, and in the watch world he is best know for designing the Lip Mach 2000 series of chronographs.  The DS stands for double security, as this range were both shock and water resistant.  This particular design was water resistant to 200M when new, which is divers watch depths and we do not know of a squared case watch that was ever certified to go deeper.  This watch features a sapphire crystal for high scratch resistance, which is not scratched or chipped.  The bracelet is unique to this watch and was made by NSA, a quality item with sprung, signed clasp for all day comfort. The bracelet has been cleaned manually.  The movement is ETA based and signed Certina 184, so we know it is the original.  It has quick set date and is working well.  We will install a brand new battery before sending the watch out to the new owner.

This watch will be supplied with the original presentation box and our Certificate of Authenticity.
