Strap for Planetarium

The lug width of the CKPT3304 is 20 millimetres. This dimension permits the use of superior-quality artisanal straps, whether in natural leather or synthetic NATO, ensuring correct adhesion to the case lugs without excessive play.

The optimal choice depends on purpose: genuine alligator emphasises the quadrant's rationality with natural geometric grain; shell cordovan offers iridescent patina enhancing chromatic depth; vegetable-tanned calf in walnut tones evolves over time; synthetic silk NATO ensures sporting practicality whilst maintaining dial legibility.

Use a spring bar tool, inserting the forked tip beneath the metal lug pin. Apply uniform inward pressure to compress the spring and unlock the strap. Repeat on the opposite lug. When reinserting, verify the pin fully enters the strap holes and the new strap is positioned perpendicularly before releasing pressure.

Yes, provided the straps have a 20-millimetre lug width and compatible thickness (typically 3–4 mm in the lug-insertion zone). We recommend artisanal straps manufactured to precise tolerances to ensure secure adhesion without excessive stress on the case lugs.

Durability depends on material and usage. High-quality alligator resists 5–8 years of moderate daily wear, with improving patina over time. Shell cordovan lasts 4–6 years before significant wear appears. Vegetable-tanned calf, being softer, requires replacement every 3–4 years. Periodic maintenance prolongs strap life considerably.
