OK, thanks. I know TAG Heuer watches are very expensive, so I suspect this applies to you, and the law is on your side in the form of The Sales of Goods Act 1972. This is how it works:
For the first four-five weeks you have a "right of rejection" - if the item you've bought breaks down, you can demand a refund.
For the next six months, you are entitled to replacement or repair of the goods. It is up to the retailer to prove there was nothing wrong with it if they wish to get out of having to do the work. And then after six months, there is still a duty to replace or repair faulty goods, but the onus is on you, the consumer, to prove that there was something wrong.
And the key time span is six years. That's how long goods may be covered by the Sale of Goods Act. It all depends on what "sufficiently durable" means. If a light bulb goes after 13 months, the consumer is not going to be overly gutted. If their washing machine goes after the same time span they are going to be livid.
The government's guidelines say: "Goods are of satisfactory quality if they reach the standard that a reasonable person would regard as satisfactory, taking into account the price and any description."
A key fact is that your relationship in the Sale of Goods Act is with the retailer, not the manufacturer.
If I were you, I would take the line of it not being sufficiently durable given the price and quality of the item. The retailer will, almost certainly, try to tell you you must go to TAG Heuer themselves, but this is NOT what the law says.
Google 'Sale of Goods Act Hub' or 'SOGA Hub' - this really useful site from Trading Standards explains the responsibilities of the retailer! It is written to help retailers understand their responsibilites, but is VERY handy for us, the consumers to know their responsibilities. Go to 'Explained' and then look at Number 3. (Oh to be able to post links! lol)
Good luck and keep posting to say how you get on.
