Thats one of the best Landeron 189 Carreras, I have seen on ebay for quite a time.
Original long minute and hour hands, dial looks perfect with no scratches or blemishes, patina seems matching and little dots intact, subdial looks clean printing good, circular ridges visible, the inner tension ring is flawless with 1% sec marks intact, pushers and crown are original, the case looks very good: sharp edges, correct backcase should have a clear longitudinal grinding if nos. However there is much material left, which can be seen at the surunding high shiny edge surface, lugs end surfaces sharp edges and slightly pointed, the serial number is correct for this generation two reference 3147 N and would date the watch around a 1968 production.I would ask for a movement picture, movement should be signed L189 under the balance and Heuer Leonidas on the bridge.
Attached out of my Heuer book please find the same reference for your reference.
I dont know the seller and my interest is to provide info for a safer purchase.
For newbies I recommend onthedash comparisions and pictures database, alexs heuerautavia website and the dealer websites of Nic, Jasper or Jonathan to make your eyes familiar with the huge heuer portfolio.
My book Heuerchronographs gives additional insights and shows 81 Heuer watches in detail and is a good investment prior new purchases.
Cheers
