Sapphire, All the Way Through

Every watch with a display back already uses sapphire to show off a mechanism worth looking at. Most stop there: a normal dial up front, the transparency saved for the back, where you only see it if you take the watch off. The Equal Force Ultimate doesn't stop there. The dial itself is sapphire — nothing standing in for the movement. If the mechanics are the actual point of the watch, covering them with a dial was always the compromise. This one just declines to make it.
