I have a whole bunch of 30Ls. I purchased my first 30LS in around 2004. I don't know how many I have now. The one on the left is an 18kt France market - it still has the sticker. The next two are Italian market. The last one is a 302 with the larger balance wheel.
The case reference number should be engraved inside the caseback: Ref. 8888-32 The front side isn't bad either. Take care, gatorcpa
Gorgeous assortment of 30L Longines. In my opinion, the cases and dial designs for the 30L movement made for some the most elegant dress watches ever made. I recently purchased a 30L watch (that still hasn't arrived yet), with a ref. number of 7163-1.
I love your 8888! It's what inspired me to get a similar reference Longines with a 30L. It's just such a simplistically elegant design and your's is so clean and crisp.
A steel 30LS was the first wristwatch that I purchased about 2 decades ago. It was so cheap at the time; there were very few Longines collectors.
