There is no better time to invest in an extremely rare 39mm tropical dial Royal Oak Kasparov, that will continue to deepen its patina over the years. We say this as a similar example (admittedly slightly more tropical) sold at Phillips watch auction in Geneva in May 2022 for a significant CHF100,000. Since then, the pre-owned watch market has had a substantial correction, creating investment opportunities like this important ref. 25860ST for collectors to snap up before prices inevitably bounce back. 

Referencing the original 39mm 'Jumbo' case size, with perfect proportions, this Royal Oak chronograph accommodates one of the slimmest self-winding chronograph calibres ever made for its time, the Calibre AP 2385. Water resistant to 50m.

Complete with its Royal Oak box, Certificat d' Origin and our 2-Year comprehensive warranty.
