CASIO AE-1700H-1AVDF

The Casio AE-1700H-1AVDF is the “Positive Display” version of the diver-style digital series you were just looking at. While the 1BVDF had a stealthy black negative screen, this model features a standard light-colored LCD with dark digits, which is generally considered much easier to read in all lighting conditions.

Key Comparison: 1AVDF vs. 1BVDF
Legibility: The 1AVDF uses a positive display, making the large digits clearer and easier to read at a glance compared to the negative display of the 1BVDF.
Aesthetic: It features a cleaner, classic sport look with a black resin case and a silver/grey LCD, avoiding the gold-tinted accents found on the inverted model.
