Identity and Attribution

The seller describes the item as a Swiss pocket watch movement produced circa 1909 by the International Watch Co (IWC) and classifies it under the period 'Early 20th Century'. The dealer listing records the movement as signed 'S & Co, Peerless, 451435, Swiss' and identifies the stock code as 'MS14 (AB-93655)'. Visible inscriptions noted in direct inspection include the serial number and 'PEERLESS' positioned beneath the balance rim, along with 'SWISS' marked on the outer plate. The reference to Stauffer & Co is not stated in the source text or present on visible markings beyond the engraved initials 'S & Co'.

Mechanical Layout and Construction

According to the source, the movement is a hunter configuration designed for stem winding and lever setting, measuring 40 mm wide by 7 mm thick. The escapement is identified in the text as a lever escapement. Visual observations of the movement record a frosted gilt bridge layout with exposed steel winding wheels finished with circular sunburst graining. The balance assembly features a balance spring and an index regulator marked with 'F' and 'S', while the train wheel bridge incorporates jeweled pivot holes set in screwed chatons.

Scope of Offering and Dealer Condition Notes

The piece is offered as an uncased movement without a case or winding stem ('It does not come with a winder'). While the seller mentions a 'white enamel' dial with 'a full set of blue steel hands' exhibiting edge damage from 11 to 2, the dial and hands are not present in the available photograph, which documents only the bridge side. The dealer characterizes the movement as having 'a good balance and spring' and rates its condition as '99% mint condition', alongside assessing the dial as '75% mint condition'. These evaluations represent dealer condition claims rather than independently verified mechanical or functional performance.
