My mistake, there are 3 different reference number for the watch....
L3.674.4.56.0
L3.674.4.56.2
L3.674.4.56.3
Emmmmmmmm.......
I am not sure where you got these numbers. If I remember correctly the last number tells the strap the wwatch is equipped with. 56 means the dial is black. 4 means stainless steel case. L3 tells you this watch is grouped under the hydro / admiral line.
harkensng,
Thanks for the info. However the lld is only available with the 'sail cloth' type strap, yet the last number has changed from 0 to 2 and then 3 over its short life span.
Additionally, from my understanding the jury is still out on the Longines numbering system. For example the number 5X denotes black dial, but the X can be anything between 0 to 9 dependent on the dial design, i.e. date window, chrono, etc.
I suspect the numbering system is not that simple.
