Markwick Markham and his son James were both fine watchmakers and worked in London. The elder was apprenticed on 25 June 1656 to Richard Taylor and subsequently to Edward Gilpin. He became free of the Clockmakers’ Company on 6 August 1666. Six apprentices were bound to him between 1674 and 1699. In 1673, he succeeded Samuel Betts’s business behind the Royal Exchange. Although he held office in the Clockmakers’ Company, he was irregular in attendance, ceasing to tend to its affairs after 1700. He worked until at least 1706. His son, James Markwick Jr., became free of the Company in 1692 by patrimony. The younger James Markwick was an eminent maker, Master of the Clockmakers’ Company in 1720 and a very early user of jewelled bearings. In later years, he was in partnership with his son-in-law Robert Markham, who succeeded him using the trading name of Markwick Markham, which became famous for watches destined for the Turkish market.
