This is a brandnew, unworn Rolex Explorer I, reference 214270, from June 2020 (NOS). It is one of the last 39mm Explorers delivered before the model was discontinued in March 2021 to give way to the 36mm.
 
This particular watch was sold by Bucherer in Zurich and spent its life in safe deposit right under Bahnhofstrasse. It remains completely unworn and comes with a full Swiss set. This includes the following:
 
Outer box
Rolex Box
Instruction manual
Guarantee card 
Guarantee manual
Rolex wallet
Purchase receipt
2 extra links (removed by Bucherer upon purchase)
 
The watch has a manufacturer guarantee of 5 years (until June 2025).
 
This is a very rare opportunity to get your hands on a NOS Explorer I Mk2!
