This is the closest comparison in mid-luxury Swiss watchmaking, because the two brands land at nearly the same price from completely different structures.
Longines belongs to Swatch Group, the largest movement maker in Switzerland. Oris belongs to nobody and has been independent since 1904.
Oris answers with a ten-year warranty and a five-day power reserve. Longines answers with scale, service and an archive going back to 1832.
The short answer
Independence against scale
Longines gets ETA calibres developed exclusively for it, several with silicon balance springs, and warranties self-winding watches for five years. Behind that sits Swatch Group’s manufacturing base and service network.
Oris built the Calibre 400 itself: five days of power reserve, strong anti-magnetism, and a ten-year warranty with ten-year recommended service intervals. Much of the rest of the range runs modified Sellita and ETA bases.
Fuller takes are in the Oris guide and the Longines guide.
Head to head
The warranty is the sharpest difference. Ten years against five, from the smaller company, which says something about how each rates its own engineering.
Power reserve follows the same direction where Calibre 400 is fitted. Five days means a watch off the wrist all weekend is still running on Tuesday, which no standard Swiss automatic manages.
Longines answers on price at the entry point and on service depth. A Swatch Group network is easier to reach than an independent’s, which matters over a decade of ownership.
| Oris (Calibre 400) | Longines HydroConquest | |
|---|---|---|
| Structure | Independent since 1904 | Swatch Group |
| Movement | Own calibre | ETA calibre exclusive to Longines |
| Power reserve | About 120 hours | Varies by calibre |
| Warranty | 10 years | 5 years on self-winding |
| Crystal | Sapphire | Sapphire |
| Entry price | About $2,100 | About $1,600 |
The catch on each side
With Oris, not every reference carries Calibre 400. Much of the range uses outside bases with the standard warranty, so the ten-year figure applies to specific models rather than the brand. Check before buying.
With Longines, the quartz models muddy the picture. A Conquest at around $900 is well made and Swiss, but it is quartz, and at that price the money buys the name rather than the mechanics.
Both share the same buying caution. Manufacturer warranties in this bracket are registered by an authorised dealer at the point of sale, and that matters most with the Oris, because the warranty is the main reason to choose it.
Which to buy
Oris if you are keeping the watch and want the money in engineering. A five-day reserve and a decade of cover is remarkable for the price.
Longines if you want a lower entry price, a deeper service network or the classical dress register. The HydroConquest is the better value at the entry point and the Master Collection has no Oris equivalent.
Neither choice is wrong, and both are considerably better uses of the money than anything in the fashion tier. The deciding question is whether you value the warranty or the network.
The three to consider
Entry points from both, plus the Oris reference to check for Calibre 400. Confirm the seller is authorised.

Frequently asked questions
Is Oris better than Longines?
On movement specification and warranty, where Calibre 400 is fitted, clearly. Longines wins on entry price, service network depth and archive.
Which has the longer warranty?
Oris, by double. Calibre 400 watches carry a ten-year warranty with ten-year service intervals against five years on Longines self-winding models.
Is Longines part of a bigger group?
Yes, Swatch Group, which also owns Omega, Tissot, Hamilton, Rado, Certina and the movement maker ETA. Oris is independently owned.
Do all Oris watches have the ten-year warranty?
No. It applies to Calibre 400 references. Much of the range uses modified Sellita and ETA bases with standard cover, so check the specific model.
Which holds value better?
Longines, modestly, because group-owned brands generally have deeper secondary markets. Neither is bought primarily as an investment.
The verdict
The independent offers double the warranty and nearly double the power reserve. The group offers a lower entry price and a service network you can actually reach.
Oris if you are keeping it, Longines if you are starting. Both are honest Swiss watches, which is more than most of this market can say.
