How ironic! Ive worn Bulova 214 and 218's over 40 years
Back n tha day when US RRs began approving electric quartz
wristies to be worn in RR service. I swapped from RR grade
pocket watches to Bulova 214. Best first quartz I ever owned.

Now I own 3 Bulovas using Precisionist movements. Thanks
for info you gave.

I don't think you will find a quartz crystal fork in the 214. It was known for an all metal fork.
