Boxed 1960’s ARSA Swiss ‘Precision’ Reverse Panda Decimal Chronograph Diver – Valjoux Cal. 23


Out of stock

From the 1960’s an honest example of an ARSA ‘Precision’ 20ATM diver decimal chronograph that has been professionally inspected in-house here at the Localtime Spa.

The large Aquastar-style stainless steel case has not been polished, houses a Valjoux Cal. 23 and measures in at 39mm or 42mm including the crown at 3h. This bi-compax chronograph has a diver’s elapsed time and GMT bezel. The reverse panda dial boasts tachymeter and decimal scales and is stunning. It is wearing one of my own tropic straps straps in black [these straps can also be purchased separately from eBay item number 132475721565]. I have included many photos, including some closeup snapshots I took just for fun, but also to allow you to enjoy the lovely details of this fine timepiece. I have recently added a nice ‘valise-type’ ARSA box that I think makes this a wonderful set.

As with all the watches we handle inhouse, the listed buy-it-now price includes a 3-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

Extra: Try my Localtime Tropical silicone straps which you can see in the last photo here and purchase separately from the store, under Accessories & Straps.

Important Note: Sometimes I am asked what I exactly mean with ‘professionally inspected by Localtime’. Here is my theory on vintage watches: as a purveyor of vintage watches, my effort is to always do only what is needed to the watch. I do not buy ‘junk’ watches to resell. I am choosy with my purchases and always sell watches that are, to my knowledge, authentic and in good condition. I first inspect the watch, both visually (cosmetically) and then mechanically. If I judge that the watch is not yet in need of a full service then I do not put the watch through a service which, by the way, entails a lot of risks too. Instead, I give it what I call my ‘Spa’ treatment which will include a cleaning, changing of gaskets, oiling, lubricating and mechanical testing. If the plexi is heavily scratched or discoloured and it can not be cleaned, I change it. If the crown is wrong or worn, I also change it. Now, if the watch is in need of a full service, then my ‘professionally inspected’ description becomes ‘professionally serviced’. In both cases, I mention what has been changed (if anything) on the watch and I include a written warranty with my listed price.

Important Note On Straps/Bracelets: The straps I use on my watches (leather, canvas, suede, rubber) are always brand new, unless otherwise mentioned and, in most cases, I also sell them separately in my store, in different colours and sizes. In the case of metal bracelets, if the watch is NOS, the bracelet is also unused. If the watch is pre-owned with its original bracelet, then the bracelet is also pre-owned, unless otherwise mentioned. Either way, if in doubt, please ask.
