Here’s the story:
My best mate has inherited his granddad’s Longines. It’s from the 70s, a solid gold piece, albeit not exactly one of the sought-after styles of today. His granddad spent the last 2 years of his life in bed, but he still loved the watch, so they had the automatic converted to a Quartz movement as he wasn’t moving enough to keep the automatic going.
Unfortunately, the original movement is nowhere to be found, but my friend would love to get it back to the original spec. On a bill from an earlier service, here’s what we have regarding info:

I’ve googled “Longines 4641” but the results show all kinds of pieces. I haven’t opened it yet, can do that if 4641 isn’t actually the reference I need.
The caliber is noted as “633”, of which I can find spare ones on eBay. However, they’re marked “633/1”, “633/2” etc.
Could anyone shed some light on what those “/1” etc mean, what we need to look for, or possibly recommend a way of finding the answer? Happy to put in the legwork, but knowing the depth of knowledge here it felt like a good place to ask.
Thanks a lot!
