The men’s Reference 5270 perpetual calendar chronograph in rose gold features a gold “Goutte” bracelet that literally blends with the case: this design is exclusive to Patek Philippe. The ebony black sunburst dial is beautifully balanced and legible, with a double aperture for the day and the month at 12 o’clock and an analog date at 6 o’clock. The chronograph indications are accentuated with sandblasted hands.
