No.
On the rare chance one remained in the dealer network somewhere, an AP Boutique could possibly tell you that. As far as the Manufacture making a new one for you to buy, no.
Now, if you owned a 26300 with a different dial like the blue or brown, you can ask an authorized AP Service Center to redial the watch for you, provided the silver dial is available for purchase.
