The Tissot PRC 100 Solar 34mm is a light-charged quartz watch, not the conventional battery-powered PR 100 34mm. Tissot says its Lightmaster Solar system charges in natural or artificial light; Swatch Group Japan says a full charge can provide 14 months of operation in darkness. That runtime is the company’s published claim, not an independently verified test result.
This is a specifications-led review brief, not a report of personal wear, timing, or charging tests. The available official details establish the watch’s design and claims, but do not settle its US price, availability, or complete US-market specifications.
What is the PRC 100 Solar 34mm?
It is the smaller-format version of Tissot’s PRC 100 Solar: a Swiss quartz watch with a solar charging system and a 34mm case. Tissot’s campaign announcement described the 34mm model as an expansion of the solar line. Swatch Group Japan’s March 2025 announcement lists four references: T151.822.11.031.00 (silver), T151.822.11.351.00 (ice blue), T151.822.22.111.00 (mother-of-pearl), and T151.822.33.021.00 (gold PVD). Tissot’s campaign announcement and Swatch Group Japan’s March 2025 announcement provide the model and design details.
Published specifications
- 34mm case and a twelve-sided bezel.
- Sapphire crystal, with solar cells beneath it, according to Swatch Group Japan.
- Swiss quartz movement using Tissot Lightmaster Solar technology.
- EOE (End of Energy) indicator.
- Super-LumiNova-treated hands and indices.
- Interchangeable bracelet options are documented; replacement strap sizing and a compatible third-party strap reference are not established in the available specifications.
Does it need a battery or manual charging?
Tissot’s campaign material says Lightmaster Solar charges from natural or artificial light and needs neither a battery nor manual charging. That describes the brand’s intended charging system; it does not mean the watch can operate indefinitely without exposure to light. The company’s wording is available in Tissot’s PRC 100 Solar 34mm campaign release.

How long does it run in darkness?
Swatch Group Japan’s November 13, 2025 product update says a full charge provides 14 months of continuous operation in darkness. Treat that as a manufacturer-published autonomy claim: the available material does not include an independent charge or runtime test, nor does it specify a testing protocol. The update is Swatch Group Japan’s November 2025 announcement.
Which dial and finish should you choose?
The four documented variants differ by dial appearance and case or bracelet finish. The prices below are Japanese tax-inclusive prices listed by Swatch Group Japan on November 13, 2025, not global prices or current US quotes.

These figures and the regional terms were published in Swatch Group Japan’s November 13, 2025 update. That announcement also described an additional one-year extension over the standard two-year warranty, for three years total, for the models it covered. Both prices and warranty terms are specific to that market and may change.
Is it the same as the PR 100 34mm?
No. Similar naming does not make them the same watch: the PRC 100 Solar 34mm is the solar quartz model, while the Tissot US page for reference T150.210.11.116.00 describes a separate PR 100 34mm with a conventional quartz movement and a listed battery voltage. That US model’s specifications must not be transferred to the PRC 100 Solar. In particular, its 100m water-resistance rating, date function, dimensions, and bracelet reference are not established here for the solar watch. See Tissot’s US page for the non-solar PR 100 34mm for the distinct model.

What is not established for US buyers?
The available official material does not establish a current US price, US availability, or a complete US-market specification sheet for these solar 34mm references. It also does not establish the solar model’s water-resistance rating or a replacement-strap size. Confirm those details for the exact reference with Tissot or an authorized local seller before buying or ordering accessories; do not rely on specifications listed for a similarly named PR 100.
