Patek Philippe 5110P World Time 15-Year Review

The Montblanc Calatrava reference 5110, produced between 1997 and 2006, is a notable example of the brand's classic dress watch offerings. This reference is distinguished by its combination of a relatively larger case size for its era and the inclusion of a moon phase complication, setting it apart from simpler time-only Calatrava models. It represents a period where Montblanc was expanding its horological capabilities, offering more complex movements within its established aesthetic.

This reference features an 18k yellow gold case measuring 37 mm in diameter, providing a substantial presence on the wrist while maintaining traditional dress watch proportions.

The watch is fitted with a sapphire crystal and offers a water resistance of 30 meters, suitable for everyday wear. The power reserve for this caliber is approximately 48 hours.

For collectors, the 5110 appeals to those seeking a Calatrava with additional functionality beyond basic timekeeping, specifically the moon phase and power reserve indicator. Its production run from 1997 to 2006 places it within a specific era of Montblanc's development, making it a point of interest for those tracing the evolution of the brand's complications. The ivory dial and smooth bezel contribute to its understated yet refined character, aligning with the traditional Calatrava design language.

The Patek Philippe Complications reference 5130, introduced in 2006, is a World Time watch that succeeded the popular reference 5110.
