How We Picked
We selected on three things we could verify — the specifications published on each live listing (movement, case dimensions, crystal, water resistance, warranty), Longines' documented brand standing as a Saint-Imier maison operating since 1832, and the seller behind the listing. Our Conquest and HydroConquest picks are both sold and shipped by Amazon.com itself, meaning the retailer of record is Amazon rather than a third-party marketplace seller; the Conquest Classic listing did not display a seller line when we captured it, so we make no seller claim there. We favored a spread of mechanisms — quartz and automatic are compared in our guide to watch movement types — plus a serious diver for readers who cross-shop our best dive watches, and a smaller-cased piece for those browsing the best women's luxury watches. Every bullet below is a fact taken from the listing itself, and where the listing is silent, we say so.
1. Best Overall: Longines Conquest 41MM Quartz Watch
Longines Conquest 41MM Quartz Watch
Longines
- Swiss quartz caliber L157 with hours, minutes, seconds, and date
- 41mm stainless steel case, 11.8mm thick, with sapphire crystal and stationary steel bezel
- Water resistant to 300 meters with a screw-down case back
- Sunray blue dial; 21mm metal band with steel triple safety folding clasp and push-piece opening
- 2 Year International Warranty
- Sold and shipped by Amazon.com
Why we picked it: The Conquest name carries real weight in the Longines catalog: per the listing, it was the first Longines collection to have its name protected by the Swiss Federal Intellectual Property Office, back in 1954. That gives this reference (L37594966) a direct line to one of the brand's defining sport-elegant families, which is exactly what a collector wants from a first or foundational Longines watch. The verified spec sheet is unusually robust for a quartz piece — sapphire crystal, a screw-down case back, and 300 meters of water resistance in a 41mm case that sits 11.8mm thick. The sunray blue dial and steel triple safety folding clasp round out a watch built for daily wear rather than the safe. Because it is sold and shipped by Amazon.com with a 2 Year International Warranty, the buying chain is as clean as the spec sheet. For most readers searching for a Longines watch, this is where we would start.
2. Best Automatic/Dive: Longines HydroConquest 41MM Automatic Watch
Longines HydroConquest 41MM Automatic Watch
Longines
- Automatic caliber L888 with hours, minutes, seconds, and date
- Water resistant to 30 bar (300 meters), with screw-down crown and case back
- Unidirectional rotating bezel
- 41mm case, 11.9mm thick, with sapphire crystal
- Steel double safety folding clasp; 5 Year International Warranty
- Dial color and band width are not stated on the listing; sold and shipped by Amazon.com
Why we picked it: If the Conquest is the everyday face of Longines sport watches, the HydroConquest (reference L37424966) is the purpose-built one — the listing describes a design inspired by water sports, and the spec sheet backs it up. You get a unidirectional rotating bezel, a screw-down crown and case back, and water resistance rated to 30 bar, which is 300 meters. For collectors, the draw is the automatic caliber L888 driving hours, minutes, seconds, and date: a mechanical movement from a maison that has been building them in Saint-Imier since 1832, in a 41mm case just 11.9mm thick. Longines backs this movement with a 5 Year International Warranty, notably longer than the two years on our quartz picks. The listing does not state the dial color or band width, so confirm the variant on the product page before buying. Sold and shipped by Amazon.com, it is the pick here for anyone who wants their Longines watch to be a true mechanical diver.
3. Best Women's: Longines Conquest Classic 2019 29.50MM Quartz Watch
Longines Conquest Classic 2019 29.50MM Quartz Watch
Longines
- Swiss quartz caliber L152 with hours, minutes, seconds, and date
- 29.5mm case, 8.7mm thick, with sapphire crystal
- Black mother-of-pearl dial; 15mm silver-tone band in a women's standard fitting
- Water resistant to 50 meters; steel triple safety folding clasp
- 2 Year International Warranty; model year 2019
- Stainless steel construction per the listing description; the page requires a size selection before purchase
Why we picked it: The Conquest Classic (reference L22864886) shows the dressier side of the Conquest lineage, scaled to a 29.5mm case that is just 8.7mm thick — proportions that read as jewelry without giving up the sapphire crystal and steel triple safety folding clasp found on its larger siblings. The black mother-of-pearl dial is the collector's hook: a natural material, so each dial has its own iridescence, paired here with a 15mm silver-tone band in a women's standard fitting. Inside is the Swiss quartz caliber L152 with date, covered by a 2 Year International Warranty. Water resistance is 50 meters, appropriate for daily wear rather than swimming with the bezel-equipped divers above. One practical note: the listing requires a size selection before you can purchase, so review the fit options on the page. As a women's Longines watch with genuine collection pedigree, it is an easy recommendation.

What to Look For
Quartz vs. automatic movements Two of our picks run Swiss quartz calibers (the L157 and L152) and one runs the automatic L888. Quartz movements are battery-powered and prized for accuracy and low maintenance — set it and wear it. An automatic winds itself from the motion of your wrist and appeals to collectors who value mechanical craft over convenience; it will stop if left unworn for a few days and simply needs resetting. Neither is objectively better: it is a question of whether you want your Longines watch to be an instrument or a small machine you live with. Notably, Longines backs the automatic HydroConquest with a 5 Year International Warranty versus two years on the quartz pieces.
Case size and thickness Case diameter is measured across the dial excluding the crown, and it shapes how a watch wears more than any other spec. The 41mm Conquest and HydroConquest sit in contemporary sport-watch territory and suit medium to larger wrists, while the 29.5mm Conquest Classic is scaled for smaller wrists or a deliberately delicate look. Thickness matters just as much for comfort: the Conquest Classic is a slim 8.7mm, while the two 41mm pieces run 11.8mm and 11.9mm — reasonable for watches rated to 300 meters. If you can, measure your wrist and compare against a watch you already own before choosing.
What water resistance ratings actually mean Water resistance figures describe static laboratory pressure, not depths you should plan to visit. As a general rule, 50 meters — the Conquest Classic's rating — covers rain and handwashing but is not a swimming spec. A 300-meter rating like the Conquest's and HydroConquest's is genuine dive-watch territory, and the HydroConquest adds the classic supporting hardware: a screw-down crown, screw-down case back, and a unidirectional bezel that can only shorten, never lengthen, an elapsed-time reading. Gaskets age, so any watch used in water should be pressure-tested periodically by a service center.
Sapphire crystal and warranty coverage All three picks list a sapphire crystal, widely regarded as the most scratch-resistant crystal in common watchmaking use and highly resistant to the everyday scratches that cloud mineral glass and acrylic over years of wear — a meaningful spec if you intend to keep a watch long-term. Warranty terms are the other durability spec worth reading: these listings state a 2 Year International Warranty on both quartz models and a 5 Year International Warranty on the automatic HydroConquest. An international warranty matters for a Swiss brand sold in the US, since service may route through official Longines channels. Keep your paperwork; warranty service typically requires proof of purchase.
Bottom Line: Which Should You Buy?
Best overall: the Longines Conquest 41MM Quartz Watch — Sapphire crystal, 300-meter water resistance, and a protected-name collection heritage in a 41mm steel case.
Best automatic/dive: the Longines HydroConquest 41MM Automatic Watch — Automatic L888 movement, unidirectional bezel, screw-down crown, and a 5 Year International Warranty.
Best women's: the Longines Conquest Classic 2019 29.50MM Quartz Watch — A slim 29.5mm case with black mother-of-pearl dial and sapphire crystal.

Frequently Asked Questions
What is the best Longines watch overall?
Based on verified listing specs, our best Longines watch pick is the Conquest 41MM Quartz: sapphire crystal, 300-meter water resistance, a screw-down case back, and membership in the first Longines collection to have its name protected by the Swiss Federal Intellectual Property Office, in 1954. It is also sold and shipped by Amazon.com with a 2 Year International Warranty. Collectors who want a mechanical movement should look to the HydroConquest instead.
How were these Longines watch picks chosen?
Each listing was opened and read at research time, and every recommendation rests on what it published: the specifications printed on each live listing, Longines' standing as a Swiss maison operating in Saint-Imier since 1832, and — where shown — the seller of record. Every factual claim in this article traces back to one of those sources.
Which Longines watch is best for men?
Both 41mm picks sit squarely in contemporary men's sizing. The Conquest 41MM Quartz is the versatile everyday choice with its sunray blue dial and 300-meter rating, while the HydroConquest 41MM Automatic adds a unidirectional dive bezel, screw-down crown, and a self-winding L888 movement. Between them, the deciding question is quartz convenience versus mechanical character — the specs are otherwise closely matched.
Which Longines watch is best for women?
Our women's pick is the Conquest Classic 2019 in a 29.5mm case, 8.7mm thick, with a black mother-of-pearl dial, sapphire crystal, and a 15mm band in a women's standard fitting. It carries the same Conquest family name as our best overall pick in a slimmer, dressier package. Note that the listing requires a size selection before purchase, so confirm the fit option that matches your wrist.
Can you swim or dive with these Longines watches?
The two 41mm models are rated to 300 meters — the HydroConquest explicitly to 30 bar, with a screw-down crown and unidirectional bezel — which is genuine dive-watch specification. The Conquest Classic is rated to 50 meters, which by standard horology guidance covers splashes and rain rather than swimming. Whichever you choose, have the seals pressure-tested periodically if the watch sees regular water use.
