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. It is powered by the automatic caliber 240 PS IRM C LU, a movement known for its slim profile and integrated complications. 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. This model maintained the distinctive World Time complication, allowing for simultaneous display of time in 24 different time zones. Its design evolved with a slightly larger case and updated dial aesthetics, distinguishing it from its predecessor while retaining the core functionality that defines Patek Philippe's travel timepieces. It was produced until 2017.

The watch features an 18k rose gold case measuring 39.5mm in diameter and 9.8mm in thickness, housing the self-winding Caliber 240 HU movement. This ultra-thin movement, visible through a sapphire crystal case back, provides a power reserve of 48 hours. The dial is silver or opaline with a guilloché center, protected by a sapphire crystal. Water resistance is rated at 30 meters.

Reference 5130 appeals to collectors seeking a sophisticated travel complication from Patek Philippe.

It combines practical complications with a robust case material, appealing to collectors seeking a blend of utility and horological complexity.

This reference features a 40.5mm stainless steel case, housing the self-winding Caliber CH 28-520 QA 24H.
