·THIS is how you do it:

Its 50 mm diameter leaves room for exceptional finishes, such as 19 jewels and the broad linear Côtes de Genève that grace the rhodium-plated bridges. This COSC-certified chronometer comes with a pedigree to match its beauty: it contains the famous 5011 pocket calibre that was so successful for Zenith in the 1960s – and in 1967 was named the most accurate chronometer ever tested by the Neuchatel Observatory. The calibre has been in continuous production since then and has been used in competition timepieces, marine chronometers, pocket watches, and watchmaking school watches.
Oscillating at 18,000 vibrations per hour, the 5011 calibre has a separate mechanism for stopping the seconds hand and synchronising the hour. It features shock-absorbers on the balance-wheel and escapement arbors, fine adjustment, and a self-compensating anti-magnetic Breguet overcoil balance spring, mobile stud-holder, double-arrow index regulator, and the Zenith winding-crown stem attachment system. All these assets combine to ensure that the watch gives a first-rate performance without losing its vintage feel.
