Patek Philippe Perpetual Calendar - 5496P-015

The 5496P-015 is a self-winding platinum cased perpetual calendar with retrograde date display. 

The case measures a comfortable 39.5mm yet only 11.19mm in height ideal for fitting under a cuff. 

The silvery dial is vertically brushed and unusually for Patek has coloured gold hour markers and hands contrasting the silver.

As with all platinum cased watches from Patek, a diamond is hidden away in the case at the 6 o'clock position a subtle indication of the case material. 

The push-pieces used to adjust the various functions are cleverly hidden between the lugs to keep the sides of the case as tidy as possible.
