Okay... first, let me say that I love davidsen's stuff! He is a true asset to the community, and his products are very unique, and very custom. As mentioned- He produces these items on his own using his resources. Good stuff in my book...
Anyways... The font issue that is mentioned is one that I noticed as well- Here is an example of not only the printed font of a Pre-V and Pre-A dial, but also some images of the markers/indicies as well...
1st, here is a comparison shot of the Pre-V style font vs. the Richemont style font post acquisition:
Note that there is a bit of a serif on the old Pre-V style...
The Pre-V and Pre-A's have the indicies a little bit more squared on the edges..
All pics above are 'borrowed' from another site.
There are some variations with the way the lume is filled in on the markers with regards to Pre-A vs. Pre-V. Pre-A is filled in more up to the edges; Pre-V is filled in less with more of the edge exposed.
Anyhow... No knock on david's items... I still think they're great, and such a service is not commonly found. Especially considering that he is always taking the forum's advice to improve his products.
