FAQ

What is the lug width of the Alexandre Meerson Altitude Officer 101OBIW?

The Altitude Officer 101OBIW is fitted with a 20 mm lug width. This is the international standard measurement for the distance between the case lugs and allows you to fit any strap of the same width. Accurate measurement of the lug width is essential to avoid ordering errors online.

What is the best strap for the Alexandre Meerson Altitude Officer 101OBIW?

The choice depends on your intended use and personal preference. For an elegant and sophisticated result, we recommend alligator or vegetable-tanned calf leather straps, which harmonize naturally with the rose gold case. For a more casual aesthetic, a canvas or nylon NATO strap represents a modern and functional choice. Vulcanized rubber remains ideal for humid or sporting environments.

How do you change the strap on the Alexandre Meerson Altitude Officer 101OBIW?

The strap is secured to the case by two spring bars (or peg bars) that pass through the lug holes. To remove the strap, you need a dedicated spring bar tool or a small screwdriver to compress the bars and release them from their seats. Once the bars are free, the strap detaches easily. Installing the new strap follows the reverse process. It is advisable to seek assistance from a professional watchmaker if you lack experience.

Can I fit aftermarket straps that are compatible with my Altitude Officer 101OBIW?

Absolutely. Any strap with a 20 mm lug width is compatible with your watch. Milano Straps offers a wide selection of artisanal straps in leather, NATO, and rubber, all available in 20 mm width. We recommend choosing a quality brand to ensure durability and precision in the strap finishing.

How long does a leather strap last on the Altitude Officer 101OBIW?

The lifespan of a leather strap depends on frequency of use, the type of tanning, and environmental conditions. A high-quality vegetable-tanned calf leather or alligator strap can last 3 to 5 years under normal use conditions. Frequent exposure to humidity, excessive heat, or UV rays shortens the service life. Regular maintenance—gentle cleaning and conditioning—significantly extends durability.
