thanks,
i already saw such watchs with steel back and gold case.
i think it is the good option, to be sure i will need to ask JLC for an extract of archives, may be one day...

you can see on the back of the horns the gold color where there is no more "chrome"

here are pictures of the back and inside

Hello i have this memovox with K855 inside and 1724488 serial on the mvt. the case seems to be made with brass and covered with chrome but as i know jlc never did that kind of case. i have shown it to official jlc shop in paris and they confirmed it's a real one but they can't say more. Can you help...
