Is the Bulova Marine Star 98D184 a real automatic watch?

Yes. It uses a self-winding mechanical movement that winds as you move your wrist, with a 42-hour power reserve. You can also wind it by hand if it has stopped.

It is rated to 20 ATM (200 m), which covers swimming and snorkeling. Avoid pressing the crown or using it in hot showers and diving, since the rating assumes the crown stays untouched.

Does it have a sapphire crystal?

No. It uses mineral glass, which resists knocks but scratches more easily than sapphire. Expect to polish out or live with fine scratches over years of wear.

How does it compare with other Marine Star models?

This version pairs the automatic movement with a steel bracelet and Roman numerals on a blue dial. Other Marine Star models use quartz movements or chronographs, which are more accurate but lack the mechanical appeal.

What should I expect in the box?

The watch on its stainless steel bracelet with a clasp, plus Bulova's paperwork and warranty card. No extra strap is typically included.

Will it keep accurate time?

Automatic movements at this level typically run within a few tens of seconds a day. Wear it regularly for best accuracy, and expect to reset it after it has been off the wrist for a couple of days.
