The "imitation wood box" is actual varnished wood. Just FYI.
Also, it seems like a bit more research about the PO before purchase would have saved you quite a bit of money. But also, your timekeeping is likely because it's an old watch and needs service; the orange PO 8500s came out over 5 years ago. If it's still in warranty, they will regulate and service the movement for free. The 8500 calibres I have are by far my most precise watches, gaining almost the exact same amount of time each day no matter the conditions.
Last, you can buy the Seamaster 300 or new PO clasp for $117, which has six micro adjustments.
More time on the forums before your next watch purchase, I'd think. [emoji6]
