Antique Bulova watches

These two watches belonged to my grandparents. They are both Bulova watches. What makes them unique is the emblem on the face. On the woman's watch, where the number 1 should be is what looks like a red cup holding a cross and flame. There are 2 drops of blood that drip down from it.

The same emblem is on the men's watch, but it is just inside the face by the number 2. I have looked under religious watches, and found nothing. I believe I was told that they recieved these watches after becoming deacons in their church. I would love to have some information on them.
