Decoding Longines reference numbers
Longines watches have references numbers of the following form Lv.w.x.y.z, for example L2.715.4.71.3. Knowing a bit about these references numbers and what they mean can help in deciphering differences between watches or making an educated guess about an unseen watch.v = category/class???w = modelx = case materialy = dialz = bracelet/strapSome examples to start showing how we can put it all together would be good. Lets start with a smallish line, the HydroConquest range.L3.644.4.56.2

Swis Army rediscovered
I was doing pretty good not buying any new watches and forcing myself to keep my favorites in a constant rotation, till I walked past the Swiss Army display at Dillards and saw these the Swiss Army 500 series divers.Though I'm not a tremendous quartz fan, in fact, the purchase of these two watches doubled my quartz watch collection to four (not including two G-Shocks), I really liked the way these two watches felt on my wrist and bought them anyway.Of course, I never pay retail, so I was able to pick these two up at substantial savings from some online retailers. I'm quite surprised at the accuracy of the quartz movement inside these watches. I have had quartz watches that gain 3, 4, 5, 6 seconds a week, but the black dial , after three weeks is only three seconds fast. The orange dial, after not quite three weeks, is still +/- 0.The black dial is the V.25024 rated at 300m water resistance and 40mm while the orange dial is the V.251174 rated at 500m, 44mm and a superb 22mm bracelet.E

All three 44mm ROO?
Does anyone have all three?I was able to have all three infront of me while at the NYC Boutique and loved them all in their own way. If I had the funds to purchase exactly all three (not unlimited funds), I could EASILY justify getting all three rather than a handful of other watches because they are each so different in their own terms- material (obviously), style, weight, color, occasion, everyday uses.Anyone else agree?
