The PRX 35 Powermatic 80 is Tissot's answer to buyers who wanted the PRX design at a wearable scale. At 35mm, this is a genuinely compact watch, not a compromised one: the integrated bracelet, flat bezel, and cushion case translate cleanly to the smaller diameter. If the 40mm PRX sits too wide on your wrist, this is the correct choice.
Tissot introduced the PRX 35 Powermatic 80 in 2023, building on the success of the 40mm Powermatic 80 that relaunched the PRX line in 2021. The movement is the Powermatic 80.111, a self-winding ETA-based caliber with an 80-hour power reserve. The 35mm case targets smaller-wristed buyers directly, as Tissot has been explicit about this positioning.
The ref T137.207.11.031.00 is the steel-on-steel variant with sunray dial and is the entry point for the 35mm lineup.
Bracelet clasp play is worth checking on any used example, as the integrated bracelet has fine tolerances and early wear can show in the clasp mechanism before anywhere else. The dial can show micro-scratches around the index markers on handled display models; inspect under raking light. The crown on the 35mm case sits close to the wrist and can be difficult to grip for winding or hand-setting, so verify smooth operation before buying.
Confirm the reference number matches the dial color you want, as Tissot offers the 35mm in several dial configurations that can look similar in listing photos.
New, the PRX 35 Powermatic 80 retails around $575 USD. The pre-owned market sits at or slightly below retail, with few premiums. This is a watch you can buy new from an authorized dealer without loss; the secondary market offers no meaningful discount that justifies taking on an unknown service history at this price point.
Demand for the 35mm is softer than the 40mm, which actually helps buyers.
The Powermatic 80.111 is rated for a 5-year service interval by Tissot, though collectors typically push to 7-10 years with normal use given the low power demands. A full service through an authorized Tissot service center runs roughly $200-300 USD depending on region and whether any parts require replacement.

Verify the case diameter is 35mm; the 40mm PRX is frequently confused with or misrepresented as the smaller 35mm variant.
