Lucky Fours vs Tissot PRX: Prices, Specs and Which to Buy

The Tissot PRX is the watch that made the integrated bracelet affordable for a generation of buyers. It is based on a Tissot design from the late 1970s, it comes from a company founded in Le Locle in 1853, and it delivers the flat case, tapering steel bracelet and framed dial of the famous Swiss sports watches for a few hundred dollars. The Lucky Fours Caspian offers the same idea for $79.99. Let us be clear before the details: the PRX is the better made watch. This page is about whether that is worth paying for.

Side by side: the quartz models

The two watches are close in concept and far apart in price. The Tissot PRX 40mm costs $450. The Caspian costs $79.99, and under Lucky Fours' current buy one, get one free offer two of them cost the same, so the comparison per watch is about $40 against $450. The Value Score puts the Caspian well ahead, mainly on price; the PRX scores higher only on warranty, because the score does not measure finishing. That is the part a buyer has to weigh for themselves.

Where the PRX is better

Finishing. The PRX case alternates brushed and polished surfaces with clean edges, and the bracelet links are tightly fitted with very little play. This is the detail that separates a Swiss watch at this price from a budget one, and it shows most in daylight, up close.

Movement. The quartz PRX runs on a Swiss quartz movement. The Tissot PRX Powermatic 80 40mm at $850 uses Tissot's Powermatic 80 automatic, named for its 80 hour power reserve, which means it will still be running after a weekend off the wrist.

Warranty and service. Tissot states two years on its product pages and has an established service network. Lucky Fours states 12 months against manufacturing defects. Over a decade of ownership, a Tissot is the easier watch to keep running.

Proportions. At 40mm with a slim case, the PRX is very close to the proportions of the original 1970s designs, which is why we call it the closest affordable version in our integrated bracelet guide.

Where the Caspian is the better buy

Price. The Caspian costs less than a fifth of the quartz PRX, and less than a tenth of the Powermatic 80. For many buyers the PRX is out of reach, and the Caspian is not.

Choice of dials. The Caspian comes in 6 colorways, including a green gradient dial and an all black version, with a horizontally ribbed texture that echoes the textured dials of the originals.

A second watch. With mix and match, a buyer can pair the Caspian with the Oceanus, which has an octagonal bezel with visible screws and a blue checkered dial, and still spend a fraction of one PRX. Our guide to octagonal bezel watches compares every affordable version of that shape.

The automatic question

Many buyers want the PRX Powermatic 80 and balk at the price. Lucky Fours does not make an automatic Caspian, so there is no like for like answer. The nearest is the Spine, an automatic in a steel octagonal case with an open skeleton dial, at $149.99. It is a busier, more mechanical looking watch than the clean PRX. If you want a clean dial and an automatic movement, save for the Tissot; if you simply want an automatic on a steel bracelet for the least money, the Spine is the one.

Design range beyond the PRX

Tissot's wider range runs from the Gentleman and Le Locle dress watches to the Seastar diver, from about $350 upward. Lucky Fours' range is built from famous silhouettes, almost all under $150. If you like the PRX because you like Tissot, our Tissot buying guide covers the rest of the catalogue. If you like it because you like the integrated bracelet, Lucky Fours has several versions, from the Caspian to the all black Brone.

Price per watch

The quartz PRX costs $450 for one watch. Two Lucky Fours watches cost $79.99 under the current offer, about $40 each, so the PRX money would buy several pairs. That is not an argument that the Caspian is the better watch. It is an argument that it is the better value for someone who wears a watch for how it looks.

Which should you buy?

Buy the Tissot PRX if you want a Swiss watch with genuinely good finishing, a movement any watchmaker can service and a two year warranty, and you can spend $450 or more without strain. It is the better made watch.

Buy the Lucky Fours Caspian if you want the integrated bracelet look on your wrist this week for under $100, you like having a choice of dial colors, or you want a second watch thrown in. The Caspian is the shape for the money.
