Odd but lovely lever-set Lonville - pocket watch conversion?

I picked this up a while ago, mainly because i love the dial design. It has some really unusual detailing with a gold reflective pattern under certain lights, with gold, ornate numerals. It is lever set, and has a diameter of around 39.5mm without the crown, so pretty large. I love wearing it, and assume it to be a pocket watch conversion of sorts. I haven't opened it up to see the movement as I don't really want to disturb it too much as it keeps great time although the 'tick' can be heard from a mile away. It's quite hard to get a decent picture showing the gold highlights without getting light reflections.

I wear it a lot - but cannot seem to find any information on it apart from one other picture of a Lonville pocket watch with the same 'circle' hands and identical number details.
