InvictaI-Force Stainless Steel Men's Quartz Watch - 46mm

Q: Are the numbers bold or thin? There are 2 versions on the pictures.

The version I bought has bold numerals. I didn't know there was another version. However it keeps perfect time within one to two seconds per month.

Q: Could you replace the strap with a metal one?

The bars (staffs) holding the ends of the strap are the same as any other watch, so any competent watchmaker should be able to fit a metal bracelet. However as the watch is quite large and heavy, fitting a metal bracelet might not be a good idea.

Q: Do you have my same problem that the stop watch hand doesn't stop on the 12 hand?

Yes, it used to stop slightly before the 12 but I corrected it. If it is a lot out have a look at the Seiko instructions here. http://www.seikowatches.com/support/ib/pdf/SEIKO_7T92D.pdf. The only difference is that button "A" is the lower button and button "B" is the upper one on your watch. Hope this helps. Let me know if this solved your problem.
