Location of Serial No. on the 2254.50, Peter Blake?

I was once a proud owner of a 2254.50 Peter Blake. Unfortunately, during a trip to Europe, I let my guard down and had my bag with the watch stolen off a train. Totally my fault, and I’m still kicking myself for it! Since that day, I’ve been looking into purchasing another 2254.50. Recently, I came across one for sale that looks superb and is priced well. However, according to the seller, the serial number was polished off, and the previous owner also replaced the bezel and crystal. If you are in the market you might know the one I’m talking about.

I purchased mine from a seller in Hong Kong in 2009 and had it serviced once while it was in my possession, during which it was polished. However, I don’t recall whether the serial number was polished off or why that would even happen. To be honest, I don’t remember if I ever saw the inside of the case or where the serial number is located on this model. I still have the box and card, so I know the serial number of my stolen 2254.50. While I’m not saying this watch for sale is my stolen one, it makes me wonder.

I’d like to know where the serial number is located on the 2254.50 and if it appears in more than one place. Regarding the watch for sale, if the serial number is located both inside the case and on the movement, and it’s been removed from both, I’d consider that a definite red flag.

I'd only buy a SMP300 without a serial if the discount were big enough.

Not being able to have it factory serviced personally is a big deal, even if these 1120 movements can be serviced by independents. To each their own, though.
