I love that this watch has an instant push button timer for 1, 3, 5, 10, 15, 20 or 30 minutes.  I have been buying this same watch for 32 years.  It is excellent for nursing moms, moms, teachers, hairdressers and anyone that needs to time things a lot.  My original watch was in white and pink but they have discontinued making that color.  So this black with blue is just fine. Each watch lasts about 3 years and is so worth the small cost.
