Taking stock in my restored scientific calculator watches.

Hello Eric!

Will see your this weekend. Yes, National Panasonic and National Radio, same thing.

Love the name “semiconductor”. Right up there with Consolidated Vultee as an aircraft manufacturer.

BoBVA, no data bank there. All the Casios are the CFX versions with SIN, COS, TAN, LOG, LN, 10X and eX as well as other transendental functions and scientific notation.

The only one missing is the Citizen Round case scientific. Have the four banger form but finding scientific engineering watches is much harder.
