Truly a spectacular piece, I think you've chosen a winner!
Interesting to hear your view of the dial as I had always thought it more of a copper color than salmon as well.
As nice as this watch is from the front, the back is the real treat IMO. How often do we see round movements in rectangular cases? This is form and function in perfect harmony and a great expression of the watchmaker's art.
Simple though it may be, I think it's among the finest and a future classic. Sometimes less is more, especially when packaged as sublimely as the 5124.
Hope that you have a lifetime of enjoyment together!
