This was probably the worst missed horological addition in the whole history of collecting the watches. Ever.
It started on eBay, quite peculiar vintage submariner appeared in my suggestions with $0.01 starting bid. Watch was in a pretty worn condition: bezel looked scratched, glass was almost matte from micro dings and the bracelet was missing. Technically nothing to look at, but since it is vintage Rolex Submariner - alright, let it be the max $5,000 bid for unserviced "as is" item. That's what I've put as a max bid and closed the app.
After a couple of days I received notification that I've been outbid, which highly surprised me, considering the insignificance of the lot. Well, I went back to eBay to have a closer look, and wait a second - there was a small logo under the crown which stated COMEX. Something significant? And I googled. It appeared COMEX is a company specialising in diving equipment which ordered Rolex to produce some small number of pieces for their divers back in the old days. Nice!
So now we have a history, vintage piece - no worries, let's make it $8,000 but that's it.
...and after a week a beaten "as is" vintage Rolex with a tiny COMEX logo under crown has been sold for over $50,000.
Why is it the worst missed addition? Because the starting price of COMEX Submariner is around $100,000. Ah!
