Late 1960’s EMMEGI ’Seamagnum 300’ 20ATU Diver Watch – ETA Cal. 2452


Out of stock

From the late 1960’s – early 1970’s a stunning EMMEGI ’Seamagnum 300’, that has been professionally inspected in-house here at the Localtime Spa.

What’s not to like on this EMMEGI ’Seamagnum 300’ from the late 1960’s? A large, Doxa-style 20ATU brushed steel cushion case with large screw-in logoed crown, ETA automatic Cal. 2452, caribbean-style bakelite decompression bezel, same-period BOR bracelet, domed plexi and a super cool bullseye dial whose colour I can only describe as bitter orange … or better yet, I’ll let the photos do the talking!

As with all the watches I inspect in-house here at the Localtime Spa, the BIN price includes a written 3-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 my own 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 in my eBay store under eBay item number 401105271426.
