Sure, take the 'z' out. So it would be dh instead of dhz. If you tap on the 'time' menu item it will list the options but for what you want just take the z out. Make the change on Sweeper copy, then you still have the original and it won't make another copy.
You can customize any watch any way you want by following those steps. Click on the portion you wish to change and go through the menu for that feature. Tap on time, text, date etc. and make the changes you want. That one automatically created a copy for you, it's a good idea to make a copy and then make the changes. Play around, you can make that same face you are using look and act totally differently.
WatchMaker is great (so is Facer), so so much you can do!
