Out of stock

This is a very nice example of a large Rotary chronograph with a manual-wind Lemania Cal. 1873 [Omega Cal. 861]. Its style refers us to the early 1970’s. It is wearing a grey G10 nylon NATO strap.

As with all the watches we inspect in-house, it comes with a 3-month written warrantee from the date of purchase. Feel free to ask us for whatever clarifications you might need.

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 & 4 colours: tan, brown, dark brown and black. We sell these separately in our eBay store under eBay item number 401105271426 and you can also see them in the last photo here.
