I dont usually go for battery watches but this one caught my eye so I grabbed it pretty cheap. Ive never owned a Hamilton and I am impressed with the quality. I dont know how to open it to see the movement but it keeps great time gaining only 10 seconds in the 2 days ive had it. To listen to it you think its running very fast because the ticks are very fast! Anyone tell me about this watch? Age or likely whats inside or how to open it?
