Inside before service.

This is afterwards. You can see that it is partly gold and partly chrome.

This is the back before service.

There is no «B» on the back.
I thought maybe the watch should be gold plated originally since they did it. Here is a photo of how it looked when I got it back.

I sent this watch to an authorized Jaeger LeCoultre dealer for full service. When I got it back the front case was «gold plated». Is this right? Was it originally in gold? I think it was much cooler in steel.
Any other information abaut this watch is appreciated.
