I have worn it for a few months off and on but prefer something a little heavier. Works great but you do need to wear it for a while and then it last a good length of time due to the automatic workings

I believe it dates back to the 60's but cannot confirm that and I have no papers/history unfortunately. 

Strap is not the original I am guessing as I can't see similar online but is a genuine Seiko strap 

Will be packaged well for shipping
