January 1970 BUCHERER “Archimedes” No-Deco Super Compressor Watch – ETA Cal. 2783


Out of stock

Professionally restored and fully serviced by Localtime and definitely the best example I’ve ever seen by far, a BUCHERER [Swiss] ‘Archimedes’ 43mm large-cased Super Compressor from January 1970 with an ETA automatic Cal. 2783.

The emerald-blue dial with no-decompression inner-bezel is simply mesmerizing and I actually photographed the watch with 3 different cameras to manage to capture it correctly [at least on some of the photos!]. To my knowledge it is the only super compressor that included a no-decompression scale on its elapsed-time rotating bezel. The watch is 100% original, including the plexi which we have nicely polished to maintain the original integrity of this lovely timepiece. Both crowns are, of course, cross-hatched. It is wearing a great quality brown calf leather strap.

As with all the watches I handle in-house here at the Localtime Spa, the BIN price includes a 6-month written warrantee from the date of purchase. Feel free to ask any questions you might have.

EXTRA! Check out my 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. I sell these separately under eBay item number 401105271426 and you can also see them in the last photo here.
