Watch is losing time quickly - loses about 20-25 minutes every 24 hours , even fully wound. Did a test where I fully wound it at 11:30 am , checked it at 7 pm and it lost about 7 minutes. Checked it at 11:30 am the next morning (24 hours) it lost about 23 minutes. 

Regular use (wore it while at work and I do a desk job) , took watch off when I got home and put it on the desk on my office. Never worn for any heavy physical activity.
