My dad's DateJust

[roadcarver]

I was talking to my dad while at a BBQ at my brother's home last week we started talking about watches.

My dad has a DateJust bought in the early early 1990's while in Manila visiting friends. He bought for himself a DateJust (tapestry dial, two tone) and a lady DateJust for my mom, TT as well.

I took at look at his watch and I noticed two things:

1. The dial didnt' have any T < 25 / T Swiss T printed on the dial at all;
2. The caseback had markings on it "Water Resistant".

He bought it from an AD in Manila.

Has anyone seen this before?

Thanks,

Vernon
