I purchased a Seiko Automatic submariner watch from you last year 2018 and it has lost time of approx 4-5 minutes per week after just 3-4 months wearing it daily! Now after consulting with Seiko UK as its ubnder 12 months old they say they will not honour the guarantee as you have not placed your dealer stamp and full details of the model and case number on the guarantee card. Iam to say the least VERY disappointed as they say there is a lot wrong with the mechanism of this supposedly Brand new Watch I purchased from you.
