"Tropical" Strap Durability?

[stockjock1975]

Hello everyone here on TRF! I had an unusual conversation with my Patek Dealer the other day and wanted to get you thoughts on the conversation. The sales person behind the counter noticed the Aquanaut 5164 on my wrist and politely complimented me on the choice. I thanked her and we began a conversation about how popular that particular model has become.....and how difficult it is for dealers to obtain.

Anyway, as I was singing the praises of the piece and it's durability, the Salesperson suggested that I still not forget to replace the strap every year or two as you would with a leather strap. Being a synthetic material I didn't feel this was necessary, but she adamantly reaffirmed that even though it's not a natural hide material, sweat, water and other items will limit its useful life to at most 2 years with normal daily wear.

Personally, I find this very hard to believe! I can't imagine the Patek "Tropical" strap not lasting at least a decade....if not even longer. Am I wrong with that? I would love to know you thoughts and experiences with this type of strap. How long can I reasonably expect it to last before needing replaced?
