Lusina Geneve Watch Information much appreciated

Hi Omega Forum Members

I've been browsing the forum for a few months now and its a treasure trove of interest and knowledge helping me get through the National Lockdown!

I found this watch with my Grandpa's belongings a couple of years back, it runs well and keeps pretty good time. I have managed to remove the movement which looks in a great condition.

I haven't been able to find much information about Lusina Geneve watches online can anyone point me in the direction of a history of the company? Would i be correct to date this watch to the 1940's?

I would also like to find a period correct leather strap for the watch if someone here could point me in the right direction.

Thanks in advanced from the UK

Many thanks for sending this, hopefully it can lead me on to find out a bit more

great bit of type on this old advert
