Morning, your low post count indicates that you may not be familiar with the features of the website, if you use the search feature located in the upper right hand side and google 81950 you will find many posts concerning the model. Also, on the home page, there are tabs that can be utilized to go to other areas of the website including information on various models,

I am not that knowledgable about the model that you posted however the model number does allow anyone to obtain additional information about it. Good Luck and enjoy your watch!
