1940’s JARDUR Ref. 850 Military Aviator Chronograph – Landeron Cal. 48


Out of stock

Professionally restored and fully serviced in-house here at the Localtime Spa, this is a rare and great example of a 1940’s vintage hand-winding aviator chronograph from JARDUR [Swiss]. Snapshots of the restoration can be seen if you scroll down the listing and we have also included some fun closeup snapshots. The case has been exquisitely re-plated [yellow gold], the Landeron Cal. 48 movement fully serviced, the beautiful black and gold gilt radium dial was lightly cleaned and domed crystal changed. Quite a huge size watch for that period, at 38mm in case diameter [40mm counting the centre crown], this classic chronograph comes on a custom made brown calf leather strap and matching yellow gold buckle, details and variations of which you can see in our eBay store, under eBay item number¬†400842595307. As with all the watches we restore in-house here at the Localtime Spa, this too will come to you with a written 6-month warrantee from the date of purchase. Feel free to ask us whatever clarification you might need.
