Citizen Tsuyosa vs Tissot PRX: Movement and Fit
On this page7
Last updated 15 October 2026
Citizen Tsuyosa vs Tissot PRX needs an exact pair. The PRX range includes quartz and automatic versions, while Tsuyosa also covers different references. Here the comparison is Citizen NJ0150-56L against Tissot T1374071104100, both steel-bracelet automatic watches with blue dials. Neither is a ranked product pick on this page.
If reserve between wears matters, the stated PRX reserve is the clearer difference in this pair. If fit matters most, shared case width is not enough to decide. Check the bracelet's rigid reach and clasp adjustment on your wrist. Unknown span measurements stay unknown. The source pages establish specifications.

Our methodology compares documented differences
We read both current US product pages and their stated fields. No wrist fitting or timing test took place. Missing sizes stay unknown. A blank field cannot become an advantage. The table compares two automatics, so a quartz PRX does not slip into the power comparison.
Our judgments concern the tasks a buyer faces. Longer reserve can reduce resets if the spring starts wound enough. The time off must also fit within that reserve. Bracelet comfort needs a physical check. Shared width and maker photographs do not prove that both will wear alike.
Reserve matters when you rotate watches
Both watches store spring power. Their stated reserves differ, so think about the normal gap between wears. A watch left off for long enough stops regardless of the number in the brochure. A partly wound start can also shorten the time before that happens.
Write down the gap you actually need to cover. Do not call a watch weekend-proof solely from its maximum reserve. Follow each caliber's startup and calendar instructions. A buyer who wears one watch every day may care less about this difference than someone who rotates several watches.
Equal width does not prove equal wrist fit
The bracelet connection and first links affect how far the watch reaches across a wrist. Case width alone cannot tell you that. The checked pages do not state the effective rigid span. This guide cannot promise a fit from the distance around your wrist.
If you can try both, check where the rigid parts stop bending and how the clasp sits underneath. If you cannot, ask for clear measurements and read the return terms. Keep a seller measurement labeled as such. Do not rename a case-length or lug-width figure to fill the missing span field.
Water use and upkeep need their own sources
Citizen labels its checked reference's water category for still-water swimming. Tissot lists a higher pressure figure for the checked PRX, but a number alone is not a full activity chart. Follow the exact manual for either watch. Neither is treated here as a documented diver's watch.
For service, ask about the actual reference and work needed. A broad brand reputation cannot supply a future repair price. Battery-replacement language for quartz is also irrelevant to this pair of automatics. Check warranty paperwork and the seller's status rather than assuming every listing carries the maker's direct-sale terms.
FAQ
Is the Citizen Tsuyosa the same size as the PRX?
The two references here share a stated case width, but that does not make their total fit the same. Bracelet reach and clasp adjustment matter too. Other Tsuyosa or PRX versions may have different dimensions. Use the complete reference code when asking for measurements or comparing a watch you already own.
Does the Tsuyosa have the same reserve as the PRX?
Not in this exact pair. The maker pages give different reserve figures for the NJ0150-56L and automatic T1374071104100. Treat them as specifications from a stated wound condition, rather than observed runtimes. A different PRX movement or another Tsuyosa reference needs its own source check before comparison.
Which bracelet is more comfortable?
This source-only comparison cannot establish a comfort winner. Wrist form, clasp position and how the first links bend can affect the result. Try the exact watches if possible. Otherwise request clear measurements and useful return terms. A shared steel material or diameter is not a substitute for checking fit.
Can you use either watch for scuba diving?
This page does not establish scuba permission for either reference. Check the exact maker's activity guidance and the watch's condition. A pressure figure and a sports-style case do not prove diver's-watch status. If diving is the intended task, look for explicit documentation for that use rather than inferring it.
Citizen Tsuyosa vs Tissot PRX verdict
Resolve Citizen Tsuyosa vs Tissot PRX with the exact versions and your wear gap. The stated reserve differs; fit still needs a separate check. Keep the missing dimensions open, and verify seller terms through the homepage buying framework before treating either as the right purchase for you.
