Want to try different straps on this 5110g, I know it is recommended to use gold spring bars on gold cases to avoid damaging the holes at the lugs. Do you follow this recommendation? Is the damage caused by using steel spring bars really something to worry about in a piece like this, where there would not be any abuse to the watch besides normal wear. 

Some of the straps I would like to try come with quick release spring bars that are certainly steel.... Thanks for sharing your opinions smile








About the Patek Philippe Annual Calendar Ref. 5110

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.

If you are very prudent when you change your strap, why not?

Good question. A potential alternative would be to ask Patek Philippe to make your custom colored straps...

Assuming that you're after custom colors, Patek Philippe has a very wide range of straps in their strap catalogue. But if you're after materials that isn't offered in their catalogue, then you're out of luck. Personally, I would avoid using steel spring bars on a watch that came with gold spring bars as there is a small chance that there would be some eventual excessive wear.

thanks for replying

yes, perhaps find straps that do not come with quick release, and just use the spring bars on the current strap
