罕有的证书（点击可放大），

关于证书的说明：

In excellent overall condition.  This watch was sold in May1805 to B & L Mertian for 768 Francs. The certificate is unusual in that the date is expressed in the French Republican character which came into use in 1792.  Only a few certificates are dated in this manner.  Souscription watches are called  by this name because they were introduced by means of a publicity brochure in 1797.  They were marketed on a subscription basis with a down payment of a quarter of the price of with each order.  Designed with a minimum number of parts to make them affordable but still of high quality and capable of accurate timekeeping.  Reliable and affordable the souscription watch enjoyed great success and attracted many new clients.  Some 700 examples were made, mainly in silver cases.  Some were fitted in silver and gold case but very few had cases of gold.  Breguet used the calibre of the souscription watch to make his first tact watches.

不是有说明了吗，是一种古时的擒纵机构（ruby cylinder escapement)，

这个是放大图，可清楚看到钢制的擒纵论被左上角的管状红宝石（有一缺口）“管制”着作有规律的运动，

在当时加工一个如此精密的天然红宝石零件可不是简单的工作。。。
