I have a bracelet watch I just got and needs proper sizing for my wrist. Are there any big risks to buying a cheap kit off ebay/amazon and doing it myself or is it worth taking it to a jewelers? I have a giftcard which works at a number of jewelers at my city center and can also be converted to an amazon giftcard so the money here is no problem. My only worry is that my watch may be damaged at the jewelers. I have no idea how caring the person doing it will be, and I am a youth plus my watch is not thousands so I don't know how seriously they will take it. I know it might sound a bit paranoid but it's a major problem to me if a new guy does it and causes some internal damage to my watch which only becomes apparent a few months later, and by re-sizing this watch I lose its warranty.
And if anyone can recommend a good place to get it done in the UK it would be great.
