Is the Invicta Speedway Ignition too big for daily wear?

At 50mm the case is large and sits high on the wrist. It suits people who like oversized watches; smaller wrists may find it top-heavy and prone to knocking against cuffs.

Does the chronograph actually work?

Yes. It is a quartz chronograph, so the subdials run from the battery movement rather than a mechanical one. That keeps it accurate and low-maintenance.

It is water resistant, but the listing does not state a depth rating. Treat it as safe for splashes and handwashing, not for swimming or diving unless a rating is confirmed.

How does it compare with other Speedway models?

The Ignition is one of the larger Speedway chronographs at 50mm. Other Speedway versions come in smaller cases and different dial layouts, so pick by wrist size and how bold you want the watch to look.

What kind of crystal does it use?

The listing does not specify, but Speedway models at this level typically use mineral crystal. It resists everyday knocks but scratches more easily than sapphire.
