How long on Processing ....roughly......approx

Afternoon.

As previous posts , ordered SB 42mm Aluminium from Apple on Monday 19th. Have a delivery time of 3-5 weeks (18th - 30th October)

Now I know this is going to be like " how longs a piece of string etc , but for those seasoned pros out there , what's the average time taken from Processing to Pteparing for dispatch ?

I'm aware it depends on country you're in , stock , which model etc.

I'm not looking for an exact answer , just those with experience of these things. I'm living in the UK.

Cheers
