Editorial
The Le Locle Powermatic 80 is Tissot's flagship dress automatic, named for the Swiss town where Tissot has manufactured watches since 1853. T006.407.16.053.00 is the steel-cased, silver guilloché variant with a white lacquered dial and applied indices, sitting at 39.3mm. At its price point, nothing else gives you a decorated automatic with 80-hour reserve and a sapphire caseback.
Tissot introduced the Le Locle line in the early 2000s as a dedicated dress automatic, and the current generation arrived with the Powermatic 80 caliber around 2014. The movement is an ETA-derived ebauche modified by Tissot parent Swatch Group for the extended 80-hour power reserve, branded Powermatic 80.111 in this reference. The sapphire caseback was added when the Powermatic 80 generation launched, making the decorated rotor visible for the first time on the Le Locle.
The line has remained largely unchanged since, with periodic dial-color additions but no case size revision. It has been in continuous production since 2013 and shows no sign of discontinuation.
Check the guilloché pattern closely before buying: Tissot offers several dial variants under similar reference numbers, and the crosshatch, barleycorn, and wave patterns are not interchangeable if you have a preference. The sapphire caseback scratches more visibly than a solid caseback; inspect it carefully on pre-owned examples. Crown and stem wear is worth checking, since the slim profile of the case puts light stress on that area over time.
The 80-hour reserve sounds generous, but if you are buying used, confirm the movement is serviced and actually holds reserve -- a worn mainspring will not reach 80 hours. Date-wheel color should match the dial tone exactly; mis-matched wheels from previous service are a known issue on lower-cost Swatch Group movements.
