This one has great sentimental value for me, despite its deceptively bland appearance. In fact, it probably would not still be in the collection if it hadn't been the watch my dad wore through most of the '50s. My grandfather (his FIL) gave it to him just before my parents were married. When he gifted it to me 5 years ago he admitted he always held a grudge, that it wasn't solid gold. Well you should have seen his face when I examined the case back and told him that it was (albeit a Wadsworth case). The cal. 351 is very clean.
