otherwise a gen one from the Panerai Boutique for $180, a lot of people say they cant see much difference between the rep rubber straps and gen, I can though and I think they are worth the extra money IMHO
Cost is fixed but value is relative and can be very subjective. An aftermarket rubber strap costs less than a quarter of the OEM strap. For 2 weeks use, I'm sure it can do the job.
