The Breitling Watch Source Forums

Not from the G.Leon Breitling era, but the first Navitimer of the Schneider era : here is the 81600 presented as " Old Navitimer" in the 1986 catalog . It nests a Lemania 1873, or 1873-24h for the Cosmonaute . The back is a snap on , very similar to pre 1980 backs . The 1st generation case is massive, with a tiny movement holder , and the 21nd generation case is less thick, with a massive movement holder . The 2nd gen case will be used in Cossies with snap on back and also in the Patrouille de France, a 1000 pieces limited edition issued in 1993.
My black beauty is a NOS Cosmonaute dated May 2006 , with original strap, box and papers. The Lemania 1873-24h has been completely overhauled due to dry oil.

beautiful and quite funnny that two of these are appearing in posts on the same day, wearing mine today and posted it in the WWAYWT thread viewtopic.php?f=1&t=32608&start=1425#p274192

Not strictly considered vintage but what a great watch.

Hi Fred,
Seen your post , nice watch and hard to find in GP ! I have a 81600 Navitimer gold plated too.

. . . but I'm pretty sure the first Navischneidertimers were those quartz versions with the unreliable movements, but I see what you're getting at.

If you get a look at the 1985 catalog scanned on this forum, you will see that Schneider was using "Navitimer" as a generic name for his Chronomat, for the Jupiter - Pluton and Mars quartz versions, for the Aerospace... and the mechanical Navitimer was illustrated as a 806 evocation . Then appeared this 81600 Navitimer with angled sliderule and Lemania inside - maybe postponed due to the legal dispute btw Breitling and Sinn?
