UMI Factory is a label that dealers write about as a workshop covering Richard Mille and Patek Philippe. The Richard Mille articles focus on how thin the case is and on whether the movement is a real geared mechanism rather than a decorated plate; the Patek Philippe articles focus on tungsten weight, plating and how much movement the buyer gets for the price. Two things matter when reading those articles: they are a seller's own account of what it stocks, and none of the listings in our own sample carries this label. We record it because it is used in public, not because we can confirm what it makes.
