This is the bezel for the early model Santos Galbe.
Both are 18k gold, but when viewed from the surface, the left side has a slightly angular impression.
The right side is slightly rounded.
If you turn this over...
The left one is solid gold. The one on the right is covered with pure gold.
Somehow, solid gold feels more luxurious and better~
Although you may think so, the cover is also made of quite thick gold.
There is no such thing as good or bad.
The initial model is said to have joined the collection in 1979, so
It seems that some parts will be solid gold for about 1-2 years after the announcement.
I assume that it will be changed to a covered item after that.
I don't know what's accurate because I don't have any documentation.
I think the reason why there are two different types of gold bezels is due to cost issues or differences in factories.
My personal opinion is that the solid bezel was made as a makeshift thing...
I once cut off the bezel of a junk Octagon product.
It is covered with the same amount of gold as the base, so it seems that the specifications are comparable to solid gold.
It seems unlikely that the gold will peel off with just a little polishing.
By the way, I have never seen Octagon's solid bezel.
If you're particular about a solid gold bezel, you'll probably want something with edges,
I've only seen it twice in the past, including SM, so it might be difficult to find it.
I think about 90% or more of it is covered.
Another difference is that there are 5 types of bracelets.
There are two types of middle cases,
There are two different types of crowns,
I believe that various specification changes were made to improve practicality until the end of production.
More about them some other day.
