Friend of mine ordered an extract for his 1920s Patek. The extract correctly notes that the dial has applied gold numerals, but it also says "tritium."

If some part of the dial (or the hands) were luminous, shouldn't it say "radium" instead since the watch is from 1926? I think the hands for the watch are skeleton type, so perhaps it means the hands were filled with luminous?

 

Call them, clear it up and get a correct extract. He paid at least $150 for it.

 

Looks like someone took a lunchbreak in the middle of the extract? Should be
something like «......Breguet numerals, radium baton hands»

 

Perhaps they have service history of the watch which tells them the hands were relumed with tritium?

 

Yes, the watch has hands with open diamonds at the ends, so perhaps they were filled with luminous when shipped from the factory. My friend sent an email asking for clarification, we'll see what Patek says.
