Frequently asked questions

Which strap material is best suited for the TAG Heuer Alter Ego WP1312.BA0750?

For this model we recommend alligator for maximum aesthetic refinement, vegetable-tanned calf for tactile evolution over time, or structured rubber for daily practicality. Your choice depends on usage frequency and colour preference: dark brown alligator enhances the steel, cognac calf offers warmth, black rubber ensures sporting versatility.

How do you change the strap on the TAG Heuer Alter Ego WP1312.BA0750?

The strap is changed by removing the spring bars that connect the strap to the case lugs. Use a dedicated tool (spring bar tool) to compress the internal springs and extract the bars. Insert the new bars into the replacement strap, align it with the lugs and compress again until locked. This is a delicate operation: we recommend assistance from a watchmaker if uncertain.

What is the average lifespan of a leather strap for this watch?

A quality leather strap (calf or alligator) with vegetable tanning has a lifespan of 2-4 years with regular wear, depending on usage frequency, climate (humidity/dryness) and maintenance. Structured rubber lasts 3-5 years. Casati Milano guarantees its handcrafted straps for 18 months and recommends periodic maintenance to extend useful life.
