TAG Heuer Carrera Chronograph Calibre 16 Automatic | AMJ Watches finance from £46.86 with 10% deposit:) TAG Heuer Carrera Black Chrono 41mm Men's Watch (fraserhart.co.uk)
Good price and not second hand!
It's a good price. However it is not a good watch. It's a tag dressed ETA 7750 and inferior in every conceivable way to the equivalent Omega speed master. Granted the Omega is 4k but can be had in a sale for low 3's and the pre-owned market is littered with examples at this money. Hard to recommend this particular watch but you have done well to find it at this money.
