Or was it 45? I can't remember anymore.
Any Perpetual that is not a Portugeuse Perpetual is difficult to read. I've worn a DaVinci, a Girard Perregaux F310b, a Master Perpetual and a Patek 3940 and I have to take my glasses of every time and stick the watch right up to my face to tell day/date/month.
The Straight Line is no different. At least for me. These watches are really about aesthetics first and practicality second.
