I've been doing a search for a pre-Moon Speedy. I've noticed that dials on the watches I've been looking at have different font weight in the subdials, even for models of the same year and reference. The varying thickness of the subdial numerals can also be seen in photos from the web. Why is this? Were there manufacturing differences or can font print get thinner over time?
You can see the variation even on this page from your website in the second image from the top: http://speedmaster101.com/105-012/
