Lemania “Double-Pusher” Royal Navy Chronograph c.1975

In 1969, the Ministry of Defence (MoD) changed its wristwatch chronograph specification from a single-pusher to a double-pusher. This was to enable the wearer to pause the timing of an event and then subsequently resume the stopwatch function. This is in contrast to the earlier single-pusher chronographs which can only reset the stopwatch function after having paused the timing.

These exceptionally rare chronographs were issued to pilots of the Royal Navy and only a mere 800 are believed to have been issued over two years, 500 in 1975 and 300 in 1976.

The 1872 calibre movement which powers the watch is primarily based upon the more famous 321 calibre movement of the early Omega Speedmasters.

The watch for sale is in wonderful overall condition and is one of the very best examples you could ever hope to find.
