I have a Bulova 23 Calendar that I recently acquired and love its look. The problem is that it is missing its pusher for the date function actuator. The actuator itself works fine and I can make the date change by depressing the actuator with a paper clip. My question is: would a watchmaker with average skill be able to make the pusher or is this a specific part that I need to locate for it? If I need to locate it, would you have a suggestion on where to start? Any and all information is appreciated. Thanks in advance.
