I post regularly on the car forum on Pistonheads and there are a number of sub-forums, one of them being watches. Seiko seem to be held in high regard by many visitors to that forum. The 'Monster' seems very popular but I believe they do not retail in the UK. Creation watches import them and many on Pistonheads have bought from them with no problems.
They are apparently a very good automatic movement and can be serviced by any decent watchmaker but most on there say they go for years without a service.
Many have also fettled with them (changed faces, altered the numbering colour on the bezel etc)
I've just had a look online at these and off the back of that I've just ordered the orange faced monster.
I wear a tag heuer formula 1 at the moment (cost me about £1500 a few years back) but it has a few scratches on the strap and outer bezel. Does anyone know a decent jeweller in London that can sort it?
