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

“WATCHES are restored to their pristine vigour, and warranted to perform well, free of any expence for one year.”
Though dated “Hartford, July 20, 1773,” Thomas Hilldrup’s advertisement in the July 23 edition of the Connecticut Journal and New-Haven Post-Boy had been composed much earlier. The same copy first ran in Connecticut Courant, published in Hartford, on May 25. It appeared in each issue of that newspaper since then, though Hilldrup dropped a short nota bene carried over from his previous advertisement after two insertions. In this latest advertisement, Hilldrup, a “WATCH MAKER from LONDON,” declared that he had already met with so much success during his brief time in Connecticut, that he had been so “IMbolden’d by the encouragement receiv’d from the indulgent public,” that he “remov’d his shop” to a new location. Prospective customers could find him at “the sign of the Dial” in the shop formerly occupied by Dr. Neil McLean near the courthouse in Hartford, “where Repeating, Horizontal and plain WATCHES are restored to their pristine vigour, and warranted to perform well, free of any expence for one year.”
After publishing this promotion in the Connecticut Courant for two months, Hilldrup extended that guarantee to readers of the Connecticut Journal. It was not the first time, however, that the watchmaker took to the pages of a newspaper printed in another town in his efforts to build a large enough clientele to allow him to settle permanently in Hartford. His advertising campaign commenced in the Connecticut Courant in the fall of 1772, but eventually expanded to the Connecticut Journal and New-Haven Post-Boy and the New-London Gazette during the winter months. The newcomer ran advertisements in every newspaper published in the colony at the time, making it clear that local watchmakers who already established their reputations among prospective customers faced some new competition. Placing an advertisement in the Connecticut Journal and New-Haven Post-Boy the first time may have been an experiment for a watchmaker who recently arrived in Hartford. Opting to place another advertisement in that newspaper six months later, however, indicated that he believed the first one had been effective in generating business beyond clients served primarily by Hartford’s Connecticut Courant. Even then, he did not consider merely announcing his presence in Hartford sufficient to draw clients to his shop. Instead, he offered a one-year guarantee on repairs to convince prospective customers to give him a chance over his competitors.
