Longines 30LS


Tmuir

Recommended Posts

All going to plan I will be picking up my Christmas present to myself tomorrow, a Longines 30LS in a 9K gold BAUME case.

I'm getting it for a very reasonable price as I am buying it from a watchmaker I know and it is a watch he has had for a number of years.

It will need a new band, but other than that is good and keeping time within a few seconds a day.

I do love the gold chatons for the jewels in the movement too.

I cant decide if the winding knob is original or not, as I have seen this model of watch with a slimmer winding knob and with ones like this, but it does look a bit chunky to me on the watch, so I may replace it if its not original.

I've picked it up and its all in pretty good shape.

The crown is a Longines crown, but I don't think the original one, so will look at replacing it in the future.

Also the second hand is not original as it is black and it should be gold. This Longines came in a Baume 9K gold case as it was sold in the UK rather than a Longines case so it does not seem to have a case number.

Any idea how to work out was the case number would be to see if Cousins has the correct second hand in stock?

 

I'm guessing one way to go would be to use Longines free service and get an Extract from Archives as stated on there website here.

I must say I'm really surprised that the extract from the archives is offered for free, but then this is the first watch I've owned that moves up a level of quality from the run of the mill watches.

    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
    • Well I’ve never seen the make before and cannot find any info, I haven’t got it just yet it’s been left to me among a 1970’s sea master and a mid size yeoman. But if anyone has any information on this one please feel free to enlighten me, many thanks
