Strap for Artelier Date 40 Generalstabsabgänger Edition / Blue

The lug width of reference 01 733 7721 4015-07 5 21 31FC is 21mm. This measurement is critical for aftermarket strap compatibility. You can verify it by measuring the internal space between the two lugs on the case. Only straps precisely engineered for 21mm will ensure a snug fit and balanced drape on the wrist.

For the Artelier, we recommend three options: alligator in brown or grey for formal elegance and aged patina development; vegetable-tanned calf for natural suppleness and chromatic evolution over time; NATO in cotton-silk blend for practicality and breathability. Your choice depends on intended use and desired colour coordination with the steel case.

You will need a spring bar removal tool to access the pins securing the strap to the case. Position the tool in the lateral groove of the lug, apply gentle pressure to compress the internal spring, and extract the strap. Ensure the new 21mm lugs are correctly inserted before releasing tension. If you are not experienced, consult a qualified watchmaker.

Yes, any expertly crafted strap with 21mm lug width is compatible. Always verify the technical specifications of the vendor: the width must be precisely 21mm, and the passant thickness must adhere to the lug without slack. Specialist craft manufacturers guarantee precise fitting standards.

A quality leather strap in vegetable tanning or alligator develops appreciable patina within 6–12 months of daily wear. Total lifespan depends on frequency of use and care: seasonal rotation with alternative straps extends life to 3–5 years. Chronic exposure to perspiration, water, and sunlight accelerates ageing. Replacement remains possible after wear, as the case itself remains unaffected.
