Does anybody here have the precise markings for a Tachymeter? I could only find the markings for every 5 seconds but not the in-betweens.

Or if not, does anybody know how to calculate it? I wanted to design a dial with a tachymeter on it but I can't figure out the precise positioning of the scale.

Use the formula...but as follows:
t = 3600/T
where T is the tachymeter marking and t is the time in seconds to determine the time for each tachymeter graduation you wish to mark. Of course, you can place any number of units on your scale...and choose as to what may be meaningful to your endeavor.
You may wish to convert to degrees: each second = 6 degrees.
