Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Master Chronometer Chronograph Stainless Steel / Sedna Gold / Blue / Alligator

The lug width of the Planet Ocean 215.23.46.51.03.001 is 22mm from shoulder to shoulder. This width is proportionate to the case diameter of 45.50mm and represents the aesthetic balance point for the model. Be sure to measure correctly the space between the case lugs before ordering a strap.

To enhance the contrast between Sedna Gold (Omega's proprietary rose gold) and black ceramic, a black alligator strap creates impeccable formal harmony. Alternatively, cognac brown alligator introduces warmth and controlled casualness. For those desiring practicality without aesthetic compromise, FKM rubber excels in water, while vegetable-tanned calf leather allows visible patina aging.

The strap is fixed via spring bars to the case lugs. Use a dedicated tool (spring bar tool) to gently compress the internal spring of each bar, extracting it from its seat. Next, insert the new strap by guiding the bar into the lug slot until you feel the spring engage securely. To avoid scratches, work on a soft, well-lit surface.

Yes, any strap with a 22mm lug width is compatible. Milanostraps offers a wide range of handcrafted straps in alligator, calf, shell cordovan, and FKM rubber, all customizable. You can choose the color, closure type (deployant or buckle), and even embroidered initials. The atelier Casati Milano also offers bespoke customization services with direct consultation.

Durability depends on material, usage, and maintenance. A high-quality alligator strap with vegetable tanning lasts an average of 3-4 years with daily wear. Shell cordovan is more durable (4-5 years), while calf is more sensitive to moisture (2-3 years). FKM rubber, suitable for swimming and diving, has extended durability (5-6 years) in marine conditions. All handcrafted straps from Milanostraps include an 18-month warranty.
