Get a real watch.
Something with a 31xx movement will do nicely if it has to be a Rowlex. That way you can save precious time and money by not having a timegrapher and simply enjoy your watch freely with confidence
Or to step it up a notch or two, you may have a look at an Omega Co-axial or quartz or even a Seiko quartz, maybe even a G-shock
Good luck.
And please get back to us with what ever direction you chose to go?
