Ernest Borel "Deep Blue" 100 m "Diver", ETA 2824-2
Great desing on clasp
and a Borel logo on the clasp I had never seen. But of course, I just recently discovered in the great Book "Automatic Wristwatches" (3 Languages! English, French and German, another reason to buy it IMO) that Borel made truly fantastic watches. I am now even happier that I had the "nose" to add all those Borel watches before I even knew that they made such great watches.
