Notes

Only seven other examples of center-seconds watches with diablotine by PATEK PHILIPPE are known to date, all in the 27000 number series, the present watch is an extremely well preserved example. The Extract from the Archives confirms that the movement of this watch was made in 1868, encased in 1872 and sold on June 12th, 1882. It is described as "20'''; lever escapement; independent sweep second chronograph, subsidiary 1/5 second. Although without a chronograph mechanism, this watch may be considered a form of chronograph. It does not of course have the return-to-zero function of the true chronograph. The 1/5th second jumping-hand or "diablotine" makes one revolution per second and therefore moves in synchronous 1/5th second steps to the balance oscillation (18000 vibrations per hour) and are simultaneously stopped and started by depressing the button on the case band. An almost identical watch is described and illustrated in "Patek Philippe, Geneve", 1993, p. 192.
