What was advertised in a colonial American newspaper 250 years ago today?

“The said Watson being a stranger, the said John Champlin doth strongly recommend him.”
James Watson, a clock- and watchmaker “Late from London,” inserted am advertisement in the December 22, 1769, edition of the New-London Gazette to inform prospective clients that he “hath lately removed from Mr. Robert Douglass, silver smith’s shop, to Mr. John Champlin, silver smith’s shop, near the new court house in New-London.” This was not the first time that Watson and his services appeared in the public prints. Just four months earlier Douglass ran another notice, also in the New-London Gazette, announcing that he “employs Mr. James Watson, Clock and Watch Maker, just from London.” Apparently Douglass and Watson quickly discovered some reason to go their separate ways. In the process, Watson pursued the same strategy for integrating into the local marketplace. Rather than open his own shop, he established an affiliation with another artisan already known to local consumers.
In the earlier advertisement, Douglass communicated a guarantee on behalf of the watchmaker, declaring that “Watson will Warrant his Work for Two Years.” Champlin made an even stronger statement of support for the newcomer: “The said Watson being a stranger, the said John Champlin doth strongly recommend him to all his customers or others.” Furthermore, Champlin endorsed Watson’s skill and character, asserting that he “will warrant his ability and fidelity in any thing he shall undertake in said business.” In so doing, Champlin staked his own reputation on the work that he expected Watson to undertake in his shop and the interactions he anticipated Watson would have with the clientele he had already established.
Champlin still considered Watson a newcomer or “stranger” after four months in New London. Prospective clients likely did as well, making it all the more important that Champlin vouched for Watson. Over time the watchmaker could demonstrate his skill to local consumers, but at the start he depended in part on forging relationships with local artisans who practiced affiliated trades, hoping that their clients would also become his clients.
