What does .025 gold content mean?

I have recently purchased an old Bulova [affil links] watch. The band in made by Kreisler and is gold plated or filled mesh and states that it has a gold cont of .025. What does this mean?

I've never seen it marked that way but the gold portions of the band might be gold filled with a total gold content of 2.5%. That would be the same percentage of gold as modern gold filled marked 12K, 1/20 - a common gold filled composition. In other words, 1/20 of the weight of the part that is marked is layered with 12K (50%) gold. Therefore: .5 x 1/20 = .025. Sounds logical to me, but who knows.
