Aug. 1975 ARSA Swiss Ref. 611504 Compressor – Wehrmachtswerk Unitas Cal. 6325


Out of stock

Professionally serviced in-house by Localtime, here we have a nice example of a rare single-crown ARSA Compressor watch with a satin blue dial in excellent vintage condition.

The solid stainless steel EPSA case measures 36mm [38.50mm with the cross-hatched crown]. The gorgeous satin blue dial, silver hands and applied indices create a gorgeous combination with the seconds’ sub-counter at 6h and date at 3h. The original plexi-glass has been nicely polished and shows no discolouration. The manual-wind Unitas Cal. 6325 [also known as ‘Wehrmachtswerk’; or ‘army movement’] is a wonderful movement, and is ticking away happily. The watch comes on a high quality dark blue calf leather strap by ColaReb [Italy] that we think fits the watch very well. I have made many photos of the watch, including some close-up macro shots and some snapshots from the service bench.

As with all the watches I service in-house, the BIN price includes a 6-month warrantee from the date of purchase. Please contact me for any questions you might have.

EXTRA! Check out our own Localtime straps: Handmade from premium calf leather to our specifications in Italy they come in 5 sizes [lug width/buckle width]: 18/16, 19/16, 20/16, 21/18 and 22/18mm & 8 colours: tan, brown, dark brown, black, cinnamon brown, olive green, denim blue and grey blue. We sell these separately in our eBay store under eBay item number 401105271426 and you can also see them in the last photo here.
