Hamilton H-40
High confidenceThe day-date member of the H-series. Recorded here because the family is otherwise easy to mistake for a single caliber in different sizes: H-10, H-40 and H-50 have different bases and different complication sets, and identifying which one a watch should contain is a prerequisite to judging what is inside it.
