Explorer 214270 authentication

[siaoju]

Hi everyone,

I’m looking to buy an explorer 215270 mark2 and I’ve found one for just under $9,100 on Chrono24. From what I’ve found before this seems like a great price so I’m a little concerned.

The condition of the watch is “very good” and the watch is sold with the original papers (no box). The seller is from Japan and has a 4.8 rating with 1,351 reviews.

This would be my first Rolex so I’d like to know what more experienced people think about this. Thanks in advance for your help, any feedback would be greatly appreciated!
