My name is Doreen and I’m new to this forum.
I’m very happy I found this forum as I’m impressed with all the useful information and with all the interesting posts and images.
I recently purchased a vintage JAEGER LE COULTREcaliber P478, movement serial number 370849, case reference number 310477, case dimensions without the crown 33.5mm with blue hands.
Dial has the SWISS on the bottom along with a beautiful vintage patina; some dirt and dust.
I will attach some images for your reference and hopefully I will get some help identifying this beautiful watch. I don’t have many knowledge about this particular brand”JLC”.
I’m interested to know as many information as possible like: year, if the dial, hands, crown are all original and belong to this particular model.
I’m also wondering if this particular model is a desirable one to add to a small watch colección.
I don’t even know if I paid to much for this one $550. I’ve seen this model selling for about $2000, of course that doesn’t mean that is the real value of the watch.
The movement is very dirty; I have to clean it and oiled soon. Also I intend to “clean”a little bit the dirt and dust from the dial. Any suggestions on how I should address this? I’m thinking on trying with a little bit of warm water and some q-tips and go very gently over the dirt and dust; perhaps just tapping slowly not rubbing. I will definitely not touch the old lume from the numbers or the hands.
The Case looks not polished for my unprofessional eye also the crown looks original but again, not sure.
Many many thanks to all who can provide some information...very much appreciated.
I’m struggling to understand what is a left winding mainspring and a right winding mainspring. Just to clarify, can anyone tell me what is the orientation on this one in the image and what the other one would look like?
