What is the best strap for the Longines La Grande Classique L4.691.7.32.6?

How do I change the strap on the Longines La Grande Classique L4.691.7.32.6?

Proceed with care using a dedicated spring bar tool to compress the small elastic pins at the strap ends, disengaging them from the case. Thread the pins into the new strap whilst maintaining compression until perfect alignment with the case holes is achieved. If you lack proficiency, consult a professional horologist.
