Invicta Speedway 42mm Men's Watch vs Invicta I-Force Chronograph 1512

The Speedway 48913 is the dressier pick: a slim 42mm steel case, blue dial and a multifunction layout that reads clean under a cuff. The I-Force 1512 is the tougher, sportier watch, with a chronograph, a date and 100m water resistance, and its 4.7 rating from 16 owners backs that up. Both run quartz and both use mineral-class crystals, so build is close; the real split is style and water resistance. Buy the Speedway for office and casual wear, the I-Force for swimming, timing and rougher use.

• Choose the Invicta Speedway 48913 if you want a slim steel watch with a blue dial that works with a shirt and doesn't look bulky on the wrist.
• Choose the Invicta I-Force 1512 if you want a chronograph with a date and enough water resistance to swim in.
