The verdict, firstCyril Favre

Buy the PRX unless The Twelve's slimmer case, original bezel and sharper finishing are worth paying extra for.

Both watches answer the same brief: a 40 mm steel automatic on an integrated steel bracelet with a textured dial, sapphire crystal, exhibition back and 100 m water resistance. The PRX is the rational default — €775 for the standard steel Powermatic 80, an 80-hour reserve and a design that has become the category's modern reference point.

The Twelve is the enthusiast's upgrade — thinner, more angular, more detailed under close inspection, and an original design that does not lean on a 1978 revival story.

The other case

The PRX is not merely the cheaper choice. Its barrel case, waffle dial and single-link bracelet are the most recognised integrated design at this price, its Powermatic 80 survives a long weekend off the wrist without a reset, and you can walk into a Tissot retailer, try it on and walk out with it. Convenience of purchase and of ownership are real features.

Where it is decided

4 arguments

Case, proportions and wrist presence

The Twelve 40 is officially 40 mm across, 9.95 mm thick and 44.5 mm lug to lug, with a twelve-sided bezel and angular multi-surface case architecture. The PRX Powermatic 80 40 is 40 mm across, about 10.9 mm thick and roughly 44 mm lug to lug excluding the first bracelet link — its flat-topped barrel case means those first links don't articulate downward immediately, so it can wear broader than the 44 mm figure suggests. The Twelve is a full millimetre thinner and its bracelet drops sooner, so it sits flatter and slides under a cuff more easily; the PRX's stance is broader and more graphic, reading as the bigger-wearing watch despite the nominally identical diameter. Try both on rather than relying on a single wrist-size cutoff.

Movement and practical ownership

The PRX runs the Powermatic 80 (ETA C07.111 architecture): up to 80 hours of reserve, 21,600 vph, a Nivachron antimagnetic balance spring, date at 3 o'clock and a mineral-glass exhibition back. The Twelve runs a Sellita SW200-1: roughly 38 hours of reserve, 28,800 vph (4 Hz), date at 6 o'clock on the standard model and a sapphire-crystal exhibition back — a COSC-certified Twelve variant exists, but that certification does not apply to this standard reference. The PRX's 80-hour reserve is the decisive practical feature for anyone who rotates watches — leave it Friday, wear it Monday. The Twelve's SW200-1 is the conventional 4 Hz architecture familiar to any independent watchmaker and runs at a visibly smoother beat, but it needs wearing or winding every day and a half.

Bracelet, finishing and design detail

The Twelve's multi-link integrated bracelet mixes brushed and polished finishing across more facets, its multi-layer textured dial carries applied indices, and it uses sapphire crystal front and back. The PRX's single-link integrated bracelet is brushed with polished accents and a triple-folding push-button clasp, its dial is the familiar waffle texture, and it pairs a sapphire front crystal with a mineral exhibition caseback. Both offer a quick-release system to compatible straps on the exact references we compare. The Twelve rewards close inspection with more finishing surfaces and dial depth; the PRX's bracelet is simpler but effective and its quick-release strap ecosystem is the better feature for a strap-changer. We can't declare a winner on clasp micro-adjustment without confirming both exact clasps' hardware, so treat that detail as unverified either way.

Price, warranty and how you buy

Tissot France lists the standard steel PRX Powermatic 80 40 at €775; the equivalent rubber-strap configuration lists lower, so confirm the exact steel-bracelet reference and current regional price before buying. The Twelve on a steel bracelet sits materially higher at current catalogued pricing — verify the exact EUR/GBP/USD figure for your reference and region, and treat any figure here as a starting point rather than a quote. Christopher Ward sells direct-to-consumer online with a return window and a movement guarantee measured in years; confirm the exact current terms before publishing or buying, since policies change. Tissot sells through Swatch Group boutiques and authorised retailers with a standard international warranty and the ability to try the watch on in person before paying. The PRX is cheaper, tryable in person and cheaper to walk away from; The Twelve costs more and is largely bought unseen, but its return window and extended movement guarantee are designed to offset exactly that. We make no resale, depreciation or investment claims for either watch.

Frequently asked

Is Christopher Ward The Twelve better than the Tissot PRX?

It depends what you're optimising for. The Twelve is thinner, more detailed and more original in design; the PRX has a much longer power reserve, costs less and can be tried on in person before you buy. Neither is objectively better — they trade differently between finishing and practicality.

Is The Twelve thinner than the PRX Powermatic 80?

Yes. The Twelve 40 is 9.95 mm thick against the PRX Powermatic 80 40's approximately 10.9 mm — nearly a full millimetre thinner, which is noticeable under a cuff.

Which has the better movement: Sellita SW200-1 or Powermatic 80?

Neither has a universal edge. The Powermatic 80 offers roughly double the power reserve (up to 80 hours versus about 38) and a Nivachron antimagnetic hairspring, which matters if you rotate watches. The SW200-1 is the more conventional 4 Hz architecture, familiar to independent watchmakers everywhere, and runs at a visibly smoother beat rate.

Is The Twelve worth the extra money over the PRX?

That depends on what you value, not a resale calculation. If a thinner case, an original bezel design and sharper finishing matter to you up close, the premium is buying something real. If you weight power reserve, price and the ability to try before you buy more heavily, the PRX is the stronger case. We make no claim about future value for either watch.

Can you swim with The Twelve and the PRX?

Yes, both are rated to 100 m, which comfortably covers ordinary swimming. Neither is marketed as a dive watch, so treat them as robust everyday watches rather than dive-timing tools.
