Yes it is. I had mine put to the right of the steering wheel (RHD car) it is a Smith's clock which nicely matches the other instruments. I don't recall the exact cost but I was surprised that it was inexpensive.
Whilst on the subject of instruments, you can specify a changed layout from standard. I asked for the speedometer directly behind the steering wheel and the rev counter on the far left, with the multi-gauge in between (this is the least important and will be obscured by your hand when driving). Depends on your priorities - I want to drive legally/safely in town and can hear what the revs are in any case. For the track, one would keep the standard layout.
