I have just purchased this one with what they say is the original crown. Haven't received it yet. Will post better pics when I do.

 

Nice! Just got mine back from service today and it's queued up for wrist time tomorrow.

 

Annnnnd it's back to the watchmaker because, after setting the date, I pushed the crown back in and was unable to wind it. Maybe next week.

 

Hate that, hope it is something simple

 

Now I have received a reply from Jennnifer.
Unfortunately, she probably mixed up my 9026-1 rose gold on steel from 1960 with my De Luxe 9025-7 from 1961
But she has contributed a lot of good information that we maby find useful. She seems to have spent much time on this.
A big thanks you to her

I will write to her again about my Conquest.

I've got a PDF file with a brochure from 1965.I don´t know how I should put it on the forum. Are you interested in it, please send me an email.

I do not know if you can open the images

Dear Anders,
Thank you for your message and the information provided.
First of all, please find here below the information of your Conquest watch you have posted on the Omega forum :

You told us the serial number is 11'613'554.
So, this serial number identifies an 18 ct rose gold wristwatch bearing the case reference 9027 and not 9026 as you're mentioning it on the Omega forum.

It is fitted with a mechanical self-winding movement, 291 caliber. It was invoiced on 17.07.1962 to the company Welsch, at the time our agent for Peru.
Nevertheless, the crown of your watch #11'613'554 looks like the original one, if we compare it with the brochures from that time (see for example page 12 of the leaflet enclosed).

Conquest DeLuxe case reference 9027
Regarding the history of the Conquest’s crowns during the time we have to admit this is not clear. After long researches in our archives, talks with experimented watchmakers, other collectors and Longines’ crowns suppliers, it appears that the name “scalloped” is not an official terminology. As a watchmaking brand, we hope you will understand that we will not use this term, which could be various from different point of views.
In addition, we confirm the crowns for the first Conquest watches, from references 9000 to 9011 launched between November 1954 to September 1957 are the same. As “ulackfocus” on Omega forum described, they look like “a picket fence with rounded off tops wrapped around the side”. They are all fitted with the mechanical self-winding movement, 19AS and 19ASD caliber.

Then, it is quite confusing. When the new calibers are fitted on the Conquests (self-winding 290 and 291) in 1959, we can see clearly 3 new crowns on different references.
The one on your Conquest #11'613'554 , can be found on cases’ references 9020, 9021, 9023, 9024, 9025, 9026, 9027, 9028, 9032, launched between October 1959 and June 1960.
Two others and are found on references 9022 (October 1959), 9027 (special edition for Italy ), 9040 (February 1961), 9041 (January 1962), 9042 (February 1962), 9044 (February 1961), 9045 (March 1965) and 9046 (April 1967).
The following Conquest’s references exist but our archives are unfortunately incomplete on this point : 9030, 9031, 9034, 9035 and 9047.

Finally, it appears that the crown on your Conquest watch with the case reference 9027 seems to be the right one, as it has been sold in Peru and not Italy.

We hope this information will be of help to you and remain at your entire disposal for any further information you may need.

Awesome stuff Anders! Email me the .pdf file when you have a chance - I'll add it to my ever-growing Longines file. If you still have the information on the 294 / 291 factory frankens that would be cool to have also.

 

Wonderful stuff. Thank you Jennifer and Anders.

 

a picket fence with rounded off tops wrapped around the side

And when this becomes the standard terminology.OF is where the legend began

 

Yeah...... I'm "legendary" for some other things actually.

 

Great stuff Anders. Thanks for the investigative work. Please give our thanks also to Ms Jennifer.
Will love information on the 291/294 frankens too as mine is one of them.

 

Thanks Anders for fwding the email and pdf. Here's the email reply from Jennifer, with the missing pictures inserted:

The PDF catalogue provided by Ms Bochut is an excellent ref as well - here's a few screenshots of the Conquests and Flagships within. Hope the Musuem is fine with us posting these material in the public domain. Anders, good job!

 

Bad news, but it was expected.
It shall have the crown that I have on my Conquest rose gold on steel. Same as Ulacfocus.

The response from Jennifer
Dear Mr.
Following your last message, I inform you that your Conquest De Luxe 9025-7 from 1961 - serial number #11’613’554 does not have the right crown.
You will find the right one on the pictures enclosed.


I remain at your entire disposal for any additional information you may require.

Best regards,
Jennifer

 

Thanks for confirming what we had long suspected: date at 12 = scalloped crown. Nice job Anders, and thanks to Jennifer!

 

+1

Glad all work producing a crown, didnt turned out being a waste of time

 

Given the ad in an earlier posting by MMMD, I would instead wager that date at 12 + produced in 1961 or earlier = scalloped crown

 

Yes, please ask Jennifer about the 1964 catalog.

 

Some more info
----------------------------------------------------------------
Dear Anders,
Indeed, we also have seen the watch have been restored (with the small engravings on the inner side of the back) and the crown has probably have been changed at that time.
Yes, we do have some in our repair shop but you will need to send us the watch for an analysis and for an estimate of the costs….


Best regards,
Jennifer

 

The "some" being the scalloped crowns!? HOLY SMOKES! Don't suppose they would be willing to sell the crowns only ...

 

The date at 12 feature on the caliber 291 only existed from late every 1959 to very early 1961 on Conquests (going by serial numbers). Longines switched that feature to the caliber 341 in 1961 for the Flagship, ceasing to make that in very early 1962. I think, but have not collected enough evidence, that the 341 then got a date at 6 option on the Admiral and maybe the Grand Prize in subsequent years.
