Genuine New Old Stock 1601 Champagne Dial? With Handset

[adiorandomhero93]

Just purchased a 1601 that came with an extra dial and handset. The seller claimed that they are both genuine new old stock. He purchased them because the dial is spotted and the hands have some corrosion on them but never got around to switching them out. Eventually I will post pictures of the head and bracelet in the vintage section, just wanted to get some opnions on the authenticity of the extra dial.

Thanks
