Strap for Planetarium

The lug width of the CKPT3344 is 20mm. This measurement represents the distance between the lugs measured from inside to inside and determines compatibility with artisanal straps. A 20mm lug width provides access to materials and craftsmanship of superior quality compared to standard 18mm or 19mm dimensions. You can measure the lug width of your own watch by positioning a digital calliper between the two lugs: the value must correspond exactly to 20mm to ensure perfect fit.

The best strap depends on intended use and personal preference. For formal contexts, vegetable-tanned alligator in opaque black creates an elegant contrast with the satin-finished steel case. For versatile daily wear, cognac-coloured calf develops a golden patina over time and guarantees extended comfort. Whisky-coloured shell cordovan offers interior lustre and extraordinary depth for special occasions. A pearl grey NATO strap is ideal for those alternating dynamic contexts whilst maintaining aesthetic cohesion. Isothermal black rubber represents the minimalist and functional choice. All materials must be compatible with the 20mm lug width.

To change the strap, proceed as follows: position the watch on a soft surface to avoid scratches. Using a small plastic lever or spring bar tool, locate the lateral pin on the first side of the lug. Gently press inward the small hook of the pin until it clicks, then pull the old strap downward. Repeat the operation on the second side. Insert the new 20mm strap by aligning it with the two holes in the lug, then click the pins into position using light pressure. Verify that the strap is stable before wearing the watch.

Yes, absolutely. The CKPT3344 is compatible with any aftermarket strap certified with 20mm lug width. Milano Straps offers a specialised collection of artisanal leather straps (alligator, calf, shell cordovan), NATO and rubber, all available in 20mm size and ready for dispatch. The use of quality aftermarket straps does not compromise the movement's warranty and allows you to customise the watch's aesthetics according to your use context. It is recommended to choose noble materials that respect the sophisticated construction of the CKPT3344.

The durability of a leather strap depends on material quality, tanning method and daily use. An alligator or calf strap in vegetable tanning, when used in rotation with other straps, can last 5-7 years before showing significant signs of wear. Shell cordovan, thanks to its density and structure, can exceed 10 years whilst maintaining aesthetic integrity. The patina that develops over time represents not a defect, but evidence of quality and conscious use. To extend longevity, it is advisable to alternate straps, protect the leather from excessive moisture and occasionally apply natural oils (food-grade lanolin or mink oil) to keep it soft and elastic.
