For sale on catawiki. Seller states it is fully original. Nice watch. But I am too new to watches to be sure of it's authenticity

I like that it has the running second sub-dial. That's something I miss on the Mido MCC.

It does. I have a 37,5mm one. Exists in 2 or 3 sizes. The big ones have the round pushers. Here's mine:

This is one I picked up a year ago. I haven't seen another with a pulsation dial. I am sure they are out there so please share.

The big ones - ref 5681 - were made in a couple of batches:
- 23074: example https://www.bonhams.com/auction/246...wristwatch-ref-5681-sold-4th-september-1946/#. Serials: 6.996m. This batch was larger than 100 pieces see i.e. https://www.christies.com/lot/lot-6028624
- 23646: example https://www.christies.com/en/lot/lot-5731472. Serials 7.402m. Delivered in 1950. Some of them have a KLM connection.
- 23787: example https://www.awco.nl/shop/type-of-watches/sports-tool/longines-one-button-chronograph-ref-5681-klm/. Also KLM connection. Serials 7.633m
- 23484: example https://curious-curio.jp/watch/31223. Serials: 7.83(?)m
- 23075: example https://shop.hodinkee.com/products/1947-longines-one-button-fly-back?variant=19148667524 (missed this reference. Large but no round pusher). Serials 10.76m

I assume the batch size was 100 pieces (but not for batch 23074). Serial numbers sequential. Marked with number on lugs and case back. For instance:
https://www.sothebys.com/en/buy/auc...gines-reference-5681-a-stainless-steel-single has serial 7402817 and is #75
https://www.christies.com/en/lot/lot-5731472 is 7402750 and #8 so 7402743 will carry #1

Interestingly I found another one described as 23075. No clue how they ended up with that number given that the caseback number has gone. Also interesting that the movement has a number which fits into the 23074 numbers. Pusher is not round. Strange one: https://www.watchnet.co.jp/en/item/view/4546

You're right. I only looked at this:


But 6.996m is 23074 territory. May be a bitsa but then is still the question what the case reference should have been. The fact that they don't tell us where it was delivered may be a hint... Also the lack of a number on the lugs is a red flag. -Edit- Matthew Bain also had it for sale: https://www.matthewbaininc.com/watch-details/2403

I think that the serial number of 23'484, 40 (Curious Curio) might start with 7'255'xxx.
Downloaded the picture



I say 7.253.573 or 7.853.578. Can't find a second one unfortunately

I can imagine some 12.68Z stop-seconds movements in the 6'996'xxx range being used for different orders (e.g. 23'074 and 23'075). Also, I realize that the example I posted above from Monaco Legends is order number 23'076 and reference 5679. Maybe the Hodinkee example is reference 5680? Below is a gold(?) example that appears to have a similar lug design and is supposedly reference 5680. EDIT: The serial number of the 5680 below is supposedly 7'020'545: https://www.collectorsquare.com/en/watches/longines/longines-other-model/ref-longines-5680/lpi

To summarize, it seems possible that:

Order 23'074 = reference 5681 (confirmed)
Order 23'075 = reference 5680 (unconfirmed)
Order 23'076 = reference 5679 (confirmed)
