Buckingham Interiors has dated this piece to the Before 1700 period.
He also worked later from Guildford in Surrey, though probably did not live there, and had the same association with Aylesbury in Buckinghamshire, where

he made the church clock in 1691 and agreed to maintain it for 31 years in return for the lease on two cottages there. He is known through only a handful of domestic clocks and through one or two watches. We know very little about his life, and even that has come to light very recently. He was probably the John Alyward of New Brentford, ‘gentleman’, who is recorded there in 1679.
