Hammer size

[Waggy]

I've been using a cheap hammer for my watchmaking antics for some time, so decided to upgrade to a 'proper one' so looked on Cousins to see, and there are way too many choices...... can anyone advise the best all-round size:

A 1oz should be about right for most work. I had 4 all different as I was also a clock maker. I also had a box wood mallet.

Ha, like OH I have 4; just weighed my most used one and it's 30 grams with the (lightweight) handle, so right at 1 ounce. There's a smaller one, and two larger. Again like OH the biggest one gets used for clock work and comes in at 55g.
