Strap for Chronomat Evolution Yellow Gold / White

The Breitling Chronomat Evolution K1335611/G570 features a lug width of 20mm. This measurement is taken with a vernier calliper inserted between the lugs at the lower part of the case, measuring the internal distance between the two lugs. Any standard 20mm strap is compatible with this reference.

For an 18k yellow gold case such as that of the K1335611/G570, the most suitable materials are vegetable-tanned alligator leather — which develops a patina that harmonises beautifully with gold — and shell cordovan for those who prefer a compact, reflective surface. In terms of colour, cognac brown and midnight blue are the two most effective pairings, offering tonal harmony and contrast respectively.

To replace the strap on the Chronomat Evolution K1335611/G570, a watchmaker's springbar tool is sufficient. Insert the forked tip into the lug hole, compress the springbar and slide the strap free. The procedure is fully reversible and requires no movement intervention. It is advisable to place the watch on a soft cloth to prevent scratches to the gold case.

Yes. As the lug width of 20mm is a widely adopted standard, there is a broad range of compatible aftermarket straps available. Milano Straps offers a selection of handcrafted 20mm straps — in alligator, calfskin, shell cordovan, rubber and NATO — available bespoke or ready to ship, fully compatible with the Breitling Chronomat Evolution K1335611/G570 without any modification to the lugs.

The longevity of a leather strap depends on the quality of the tanning, daily use and maintenance. A high-quality vegetable-tanned alligator or calfskin strap, used with care — avoiding prolonged immersion and excessive moisture — can last between three and six years while retaining its structural and aesthetic integrity. Periodic application of a neutral leather conditioner significantly extends the strap's service life.
