I guess that among watch collectors, Longines is mostly know for their military-, diver- and chronograph watches… But the brand also have a long tradition of making time only “dress” watches.
I say “dress” watches due to that what they would be considered as today. Originally…
Originally they were sold as waterproof watches, like the Longines Conquest I share earlier or like this Longines reference 104 Flagship.
The Conquest and the Flagship, T.W.O models of the rich Longines heritage!

Longines had a series of Flagship watches, all the way from the automatic De Luxe down to the manual time only.
here is a couple scans from the 1961 Longines catalogue showing several different versions, the De Luxe.

Time only, time with date, all with automatic movements.

The reference 104 has a manual movement Calibre 30 LS, based on the movement number from 1959. Not very decorated, but still easy on the eye.

Longines often had very nice case back engravings and so also on the Flagship, a bit faint but the “104” is still clear.

A nice detail is the Flagship logo on the inside of the case back, and the reference 104 5 – I am guessing the fifth iteration of this reference.

This 35.5 mm stainless steel case with gilt hands and index makes a very elegant waterproof watch!

In the U.S. market, Longines had a relationship with both Wittnauer, Vacheron Constantin and LeCoultre…
Stay tuned, as we soon will start to explore this topic.
