Frequently asked questions
What is the lug width of the Omega Seamaster Planet Ocean 215.98.40.20.01.001?
The lug width is exactly 19 mm. This measurement is taken by measuring the space between the spring bar pins at the case lug level. Make sure to measure it correctly to ensure perfect compatibility with aftermarket straps.
Which strap is best suited for the Seamaster Planet Ocean 215.98.40.20.01.001?
Vegetable-tanned alligator represents the most elegant formal choice, particularly in cognac or brown shades. For everyday use, box calf offers versatility and pleasant aging. For sports contexts, an FKM rubber or NATO strap ensure practicality and durability.
How do you change the strap on the Omega Seamaster Planet Ocean 215.98.40.20.01.001?
The strap is changed by using a spring bar tool to compress the spring pins positioned at the lugs. Apply gentle pressure on the lower side of the lug to extract the pin, then insert the new strap by aligning the holes with the pins and release. Proceed carefully to avoid scratching the titanium case.
Which aftermarket straps are compatible with reference 21598402001001?
All straps with 19 mm lug width are compatible. Milano Straps offers straps in alligator, calf, shell cordovan and FKM rubber, all customizable and guaranteed for 18 months. The Casati Milano atelier also offers bespoke tailoring with direct selection of hides.
How long does a natural leather strap last on the Seamaster Planet Ocean?
A superior quality leather strap lasts on average 3-5 years with ordinary maintenance and rotation with other straps. The natural aging of vegetable-tanned leather is desirable and adds character. Construction quality and type of leather significantly influence longevity: cordovan lasts longer than standard calf.
