Tissot Powermatic 80.111 / ETA C07.111

Verdict: Good, well-rounded calibreMovement Honesty: ETA-derived Swatch Group movementHigh confidence

Buyer meaning: Good for a Tissot PRX buyer because 80 hours means the watch can sit over the weekend and still run. The tradeoff is a slower beat rate than a classic ETA 2824-2 and less traditional-watchmaker-friendly regulation than old-school ETA service logic.

!Official Tissot PRX product copy may mention Nivachron. WatchBase lists C07.111 as part of the C07.1XX synthetic escapement family. C07.811 is the Powermatic 80 silicon balance spring variant. Do not treat Nivachron, synthetic escapement and C07.811 silicon as interchangeable without exact variant sourcing.

Strengths & weaknesses

Strengths

  • 80-hour power reserve is excellent daily convenience at this price point
  • Real mechanical date automatic with hand-winding and hacking seconds
  • Strong value inside Tissot PRX and other accessible Swatch Group watches
  • WatchBase-backed ETA C07.111 identity, not unsupported 80.211 codes

Weaknesses

  • ETA 2824-2-derived, not in-house manufacture
  • 3Hz beat rate trades away classic 2824-2 frequency
  • No conventional regulator; less traditional-watchmaker-friendly than old ETA 2824-2
  • Balance spring / escapement details vary by Powermatic variant and source

Why this movement matters

Power reserve

80 hours means you can take the watch off over a weekend and it will usually still be running Monday morning. That is a genuinely useful reserve for a daily wearer, not just a marketing rounding exercise.

Frequency

21,600 beats/hour / 3 Hz is a common modern automatic rate. Higher frequency can improve stability in some conditions, but service access and long-term ownership matter more than Hz alone.

Certification

Not chronometer certified by default; WatchBase notes C07.111 can be chronometer-certified on specific variants means the movement passed an independent timing standard before leaving the factory. That is useful, but it does not replace long-term ownership feedback or service network access.

Serviceability

Serviceability is more nuanced than a classic ETA 2824-2. The C07.111 is ETA-derived and Swatch Group-backed, but it has no conventional regulator and uses Powermatic-specific architecture. WatchIntel should not claim that any competent watchmaker can service it cheaply, that parts are universally available, or that it has a fixed service cost or interval. Best handled through Tissot / Swatch Group service or watchmakers familiar with Powermatic 80 architecture.

Movement origin

WatchIntel classifies this as ETA-derived Swatch Group movement. Origin labels matter because they affect service access, resale narrative and whether marketing language matches what is actually inside the case.

Finishing

Industrial entry-level finishing; branded rotor on many Tissot watches Finishing on tool-watch calibres is often practical rather than exhibition-grade. That is not automatically a flaw if the movement is robust and well regulated.

Score breakdown

Architecture68/100

ETA 2824-2-derived architecture heavily modified for 80h reserve; practical, not exotic.

High confidence
Precision & regulation64/100

No generic COSC claim; factory regulation can be good, but not chronometer by default.

Medium confidence
Power reserve / usability92/100

80h reserve is excellent at this price point.

High confidence
Robustness68/100

Broadly proven Swatch Group family, but C07.111 synthetic escapement and no conventional regulator need explanation.

Medium confidence
Serviceability58/100

Not as simple as classic ETA 2824-2 from an independent-service perspective; avoid any-watchmaker claims.

High confidence
Originality / honesty62/100

Not in-house, but a meaningful Swatch Group evolution of ETA 2824-2.

Medium confidence

Industrial entry-level finishing; branded rotor is not haute finishing.

Movement honesty

Movement Honesty: ETA-derived Swatch Group movement

Public label: ETA-derived Swatch Group movement

A known base calibre with meaningful brand-specific modifications, modules or regulation work.

Source nuance: Powermatic 80 is not a Tissot in-house movement. It is an ETA / Swatch Group movement derived from the ETA 2824-2 platform. That is not bad. It is exactly why the movement delivers strong value. But WatchIntel should not oversell it as manufacture or old-school ETA service simplicity.

The ETA C07.111, commonly branded by Tissot as Powermatic 80.111, is an ETA 2824-2-derived automatic movement redesigned for an 80-hour power reserve. WatchBase lists it with 25.60mm diameter, 23 jewels, 80h reserve and 21,600 frequency. CaliberCorner also lists 23 jewels, 21,600 bph / 3Hz, hand-winding and hacking seconds. The honest WatchIntel framing is: this is a very strong consumer-value movement because of the 80h reserve, but it is not simply a normal ETA 2824-2 and not automatically as independently service-friendly as the old 2824. The reduced beat rate, no conventional regulator and variant-specific escapement details matter.

WatchIntel never overclaims "in-house" without source nuance. Manufacturer marketing language may differ.

About this movement

Tissot Powermatic 80.111 / ETA C07.111 is an automatic date calibre derived from ETA 2824-2 and redesigned for an 80-hour power reserve. WatchBase lists 25.60mm diameter, 23 jewels, 21,600 bph and C07.1XX synthetic escapement. Powermatic 80 family variants include C07.111 / 80.111 (23 jewels, C07.1XX synthetic escapement), C07.611 / 80.611 (25 jewels, regular escapement) and C07.811 / 80.811 (25 jewels, silicon balance spring). Do not mix variant specs on the C07.111 page.

Serviceability

Serviceability is more nuanced than a classic ETA 2824-2. The C07.111 is ETA-derived and Swatch Group-backed, but it has no conventional regulator and uses Powermatic-specific architecture. WatchIntel should not claim that any competent watchmaker can service it cheaply, that parts are universally available, or that it has a fixed service cost or interval. Best handled through Tissot / Swatch Group service or watchmakers familiar with Powermatic 80 architecture.

Value context

Very strong inside Tissot PRX and accessible Swatch Group watches, but not a serviceability legend.

Frequently asked questions

What is ETA Powermatic 80.211?+

Do not publish ETA Powermatic 80.211 unless a direct source proves that exact code. For the linked Tissot PRX T137.407.11.041.00, WatchBase identifies the movement as ETA C07.111, commonly branded as Tissot Powermatic 80.111.

How many jewels does the Powermatic 80.111 / C07.111 have?+

23 jewels. The previous WatchIntel value of 21 jewels was wrong for C07.111.

What is the frequency of Powermatic 80.111 / C07.111?+

21,600 bph / 3Hz. Do not display 6Hz.

Is Powermatic 80 based on ETA 2824-2?+

Yes. WatchBase identifies C07.111 as based on ETA 2824-2. But it is not simply an unchanged 2824-2: the beat rate, power reserve, regulation and escapement details differ.

Is Powermatic 80.111 easy to service?+

More nuanced than the old ETA 2824-2. It is Swatch Group / ETA-derived, but C07.111 lacks a conventional regulator and has Powermatic-specific architecture. Avoid saying any watchmaker can service it cheaply unless source-backed.

Does C07.111 have a silicon balance spring?+

Do not say this generically. WatchBase identifies C07.811 as the Powermatic 80 silicon balance spring variant. C07.111 should not automatically inherit C07.811 features.

Does the Tissot PRX use C07.111?+

WatchBase lists Tissot PRX T137.407.11.041.00 as using ETA C07.111. Current official Tissot product copy may use consumer-facing wording such as Powermatic 80 and Nivachron, so store exact sources per reference and date.
