Tissot PRX Quartz vs Automatic: Which Suits You?
On this page7
Last updated 15 October 2026
Tissot PRX quartz vs automatic starts with power and daily use. This page compares two blue-dial 40 mm watches: T1374101104100 and T1374071104100. They share a broad case style. One uses quartz; the other uses a spring-driven automatic movement.
Choose quartz if you want a watch that needs no winding. Choose automatic if you want the mechanical movement and accept resets after its reserve ends. Both checked watches use a steel bracelet and sapphire crystal. Their thickness differs, but that figure cannot prove comfort or cuff clearance. Neither is selected here as a live product pick.

Source pages checked 15 October: quartz reference and automatic reference. Tissot labels the length as case length. We do not rename it physical lug-to-lug or effective bracelet span.
Our methodology uses current Tissot specifications
We read the exact US pages and compared their stated fields. No wrist trial or timing test took place. The table keeps case widths matched. A size difference should not look like a movement difference. These facts do not apply to every PRX size or dial.
The choice below concerns daily tasks. We do not claim a measured rate advantage or quote a service bill. An under-budget pick needs a current offer check too. A maker's page cannot prove another seller's warranty terms. It cannot show that seller's new stock either.
The power routine is the larger difference
The quartz watch needs its stated electrical supply. Wearing it does not wind a spring. The automatic stores power in a mainspring and winds through motion. Left off long enough, it can stop and need a reset. Its stated reserve assumes a sufficiently wound start.
For a watch you wear only on occasional evenings, think about that reset. You may enjoy it, or you may prefer to put the watch on and leave. The movement you want to own is the one whose routine suits you, rather than the one with the more interesting brochure description.
Thickness and bracelet fit need separate checks
The automatic is thicker in this pair. That is a stated size, not a comfort test. Fit still depends on the case and how the bracelet bends. Check that the clasp can reach a useful size for your wrist. Look at how the first links sit too.
Tissot lists the same main bracelet reference for this pair. Do not treat that as proof of identical feel on every wrist. Neither checked page supplies a verified effective rigid span. If that dimension decides fit, request a clear measurement rather than deriving it from case width.
Maintenance and warranty are not one price
Battery work and mechanical service are different tasks. The cost depends on the work needed and where you send it. Ask for a quote for the exact watch. Check what it includes. If water use matters, ask about seal checks after case work.
Read the seller's warranty and return terms before sizing the bracelet. A maker's published warranty does not automatically apply to every purchase channel. Keep the complete reference and purchase record. The homepage buying framework helps keep those offer checks separate from the movement preference.
FAQ
Are the quartz and automatic PRX the same size?
Matched references can share a case width while differing in thickness. The two 40 mm references here do exactly that. Other PRX sizes need their own comparison. Check the complete reference code and published dimensions before using one pair's data to judge a different watch in the range.
Does the automatic PRX keep running in a drawer?
It can keep running while spring power remains, then stops once that reserve ends. The stated maximum does not prove that it started fully wound. If you rotate watches, expect to set it after a long break. Follow the matching manual for startup and calendar setting rather than improvising.
Is the quartz PRX a lower-quality watch?
Movement type does not settle the quality of the complete watch. The matched references share several stated case features, while their power systems differ. Choose the routine and fit you want. This guide has not measured accuracy or durability, so it does not turn a movement preference into a test result.
Is the PRX case length the bracelet span?
No. A published case-length field does not establish the outer span of rigid bracelet parts. Keep those measurements separate. If the maker does not publish the span, mark it unknown or measure the actual watch with a clearly stated method. Do not fill it from the case width.
Tissot PRX quartz vs automatic verdict
For Tissot PRX quartz vs automatic, decide the power routine first. Then compare the matched reference's case and bracelet fit. Keep service quotes and seller terms separate. You can prefer either movement without claiming the other is a worse watch or assuming that a familiar case fits your wrist.
