TAG Heuer
S/EL WG1213.BA0435— lug 18mm

The lug width of the TAG Heuer S/EL WG1213.BA0435 is 18 millimetres. This dimension requires specifically sized 18mm straps, which are not interchangeable with standard common sizes like 20mm. To verify correct measurement, position a tape measure perpendicular to the case, spanning from one side to the other of the strap seat.

For the elegant proportions of the WG1213.BA0435 we recommend cognac brown alligator for formal contexts, vegetable-tanned calf which develops natural patina over time, or NATO cordura for everyday versatility. The stainless steel case benefits from materials that do not compete visually: avoid heavily textured surfaces that might overload the wrist.

Strap replacement requires a spring bar tool or professional instrument. Remove the spring bars from opposite sides of the strap seat, extract the used strap and insert the new one, repositioning the spring bars. If you prefer, Casati Milano atelier offers strap change with consultation on materials and colours, ensuring the operation without risk to the case.

Yes, provided the lug width is exactly 18mm. Compatible artisanal straps are available online, customisable in leather, colour and stitching. The Casati Milano atelier produces made-to-measure straps with choice of leathers and 18-month warranty, ensuring total compatibility with your original spring bars.

A quality leather strap, such as alligator or vegetable-tanned calf, typically lasts 3-5 years with regular use. Lifespan depends on exposure to water, humidity and frequency of use. Straps produced by Casati Milano include an 18-month warranty and may be regenerated or replaced over time, allowing sustainable management of the accessory.
