Out of stock

Professionally serviced by Localtime, one of the largest classically-designed chronographs, this ROTARY 20ATU chronograph from the 1960’s measures in at 43mm [or 45.85mm including the large screw-in crown].

It runs on a Valjoux Cal. 7736 and is wearing a handmade premium calf leather strap in tan brown.

As with all the watches I inspect in-house here at the Localtime Spa, the BIN price includes a written 6-month written warrantee from the date of purchase. Feel free to contact me for whatever 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.
