You can also send a message to
[email protected] mentioning the serial number (11'722'291) and ask them to provide you some details. Usually they answer within 24 hours and then you can corroborate their answer with the information you have (i.e., confirm whether this movement was built in a Flagship or not and when it was sold and to which retailer).
Based on this information I caught once a seller who was trying to pass a watch as a Conquest, but Longines said that the serial number of the movement wasn't built into a Conquest.
Which does not make the competent information provided by Dennis superfluous.
