The Best Dive Watch Under $2,000: HydroConquest vs Ocean Star vs Prospex
Two thousand dollars is the most interesting budget in watchmaking. Below it you are choosing between honest tool watches; above it you start paying for a name. Right on the line sit three divers that could each be someone's only watch for twenty years — the Longines HydroConquest, the Mido Ocean Star and the Seiko Prospex. They are not the same watch at three prices. Here is what actually separates them.
The verdict first
- Best overall: Longines HydroConquest 39 mm — 300 metres, a ceramic bezel, a silicon hairspring and a five-year warranty, in a case thin enough for a shirt cuff.
- Best value: Mido Ocean Star 200 — eighty hours of power reserve for around half the money.
- Best under $700: Seiko Prospex SPB117J1 — sapphire, 200 metres, seventy hours, 39.5 mm.
- Best for a smaller wrist: Mido Ocean Star Tribute at 40.5 mm, or the HydroConquest 39.

What the numbers do not tell you
Thickness is the specification that decides everything
Every dive watch is water resistant enough. What separates one you wear daily from one that lives in a drawer is whether it goes under a cuff, and that is thickness and lug-to-lug, not diameter. The HydroConquest 39 is 11.7 mm thick with 48.1 mm between the lug tips — genuinely unusual for a 300-metre watch, and the single strongest argument for paying the Longines premium.
Power reserve is the specification you feel
Eighty hours (Mido), seventy-two (Longines), seventy (Seiko). All three survive a weekend off the wrist; a 41-hour movement does not. If you own more than one watch, this is the number that decides whether you spend Monday morning resetting the date.
The bezel is where the money shows in five years
An aluminium insert picks up scratches from doorframes in the first month. Ceramic does not. The HydroConquest has ceramic as standard; on the Mido you get it by choosing the Ocean Star 200C for about sixty euro more, which is the easiest upgrade decision on this page.
Warranty is not a footnote
Longines gives five years internationally. That is two or three more than the industry standard, on a mechanical object you intend to keep. Over a twenty-year ownership it is worth more than most of the specification differences above it.
The four we would actually recommend
1. Longines HydroConquest 39 mm — the one to buy if you buy one
L3.779.4.56.6, €1,870 at the time of writing against an Italian list of €2,200. Ceramic bezel, 300 metres, L888 with a silicon hairspring that ignores the magnets in your phone case and your laptop. If 39 mm is small for you, the 41 mm L3.742.4.96.6 is nearly six hundred euro cheaper.
2. Mido Ocean Star 200 — the value answer
M026.430.11.041.00, around €915. Swiss, 200 metres, sapphire treated on both faces, and that eighty-hour Caliber 80. You give up the Longines finishing and the ceramic bezel; you keep roughly nine hundred euro.
3. Seiko Prospex SPB117J1 — the value floor
SPB117J1, €640, 39.5 mm, sapphire, 200 metres, 6R35. There is no honest argument that anything below this price does the job better. Its bigger brother, the 41 mm SPB317J1, is the one for open water.
4. Maurice Lacroix Pontos S Diver — the one nobody expects
Just over the line at about €2,070, the Pontos S Diver in all steel with a white dial is the contrarian pick. White-dialled divers are rare and they age better in photographs than any black one.
How to choose in one paragraph
If the watch has to work with a jacket as often as with a wetsuit, buy the HydroConquest 39 and stop reading lists. If the money matters more than the last ten per cent of finishing, buy the Ocean Star 200 — nothing at that price gives you eighty hours. If your budget is firm at seven hundred, buy the Prospex SPB117J1 and be quietly pleased for a decade.

An example, with the numbers from our own product page. The Longines HydroConquest L3.779.4.56.6, 39 mm lists at €2,200 in Italy — and every Italian list price already has 22% VAT inside it, so on a counter in Genoa that is about $2,623. Our price is €1,870: 15% off list before anything else happens.
Then the parcel leaves the European Union, the Italian VAT comes off before you pay, and the figure you actually put on your card is $1,828. Set the two side by side and it is 30% less than an Italian pays for the identical watch, in the identical box, with the same international warranty card inside. Import duty goes on top of that, and the product page estimates it for you before you order — no surprises at the door.
Ordering from the United States: what actually happens
Cicala is a family jewellery house in Genoa, on the Italian riviera. We opened in 1950 and we still sell out of a real boutique with a watch bench behind it. Shipping a watch to an American address is ordinary work for us, and there is nothing hidden in how it is priced.
- The site switches to dollars. Pick the United States in the Ship to selector and every price on the site is converted, at a rate we refresh daily.
- The 22% Italian VAT comes off before you pay. Deliveries outside the European Union are exempt from it. The product page shows both figures side by side — the Italian shelf price, and yours.
- Import duty is printed on the page, not sprung on you at the door. The United States ended the $800 de minimis exemption in August 2025, so every parcel is now dutiable. Each product page carries an estimated duties-and-clearance line and a delivered to your door total. The courier collects that amount; it never passes through us.
- Every shipment is insured, tracked and unmarked. Nothing on the box says what is inside — see shipping and costs.
- The warranty travels with the watch. New watches arrive with the maker's international warranty card, on top of the 24-month Italian legal warranty of conformity: the details are on the warranty page.
- Fourteen days to change your mind, under the returns policy, and card, PayPal, Apple Pay, Google Pay or bank transfer at checkout.
The arithmetic worth remembering: as long as the duty rate is lower than the 22% VAT you are not paying, the watch lands in the United States for less than it costs on an Italian counter — and usually less than the American list price too. Tariff rates have moved several times since 2025, so trust the live figure on the product page rather than any number you read in an article, this one included.
Frequently asked questions
What is the best dive watch under $2,000?
The Longines HydroConquest 39 mm, for a specific reason: 300 metres and a ceramic bezel in a case only 11.7 mm thick and 48.1 mm lug to lug, with a five-year international warranty. If value matters more than finishing, the Mido Ocean Star 200 does 200 metres and eighty hours of power reserve for roughly half.
Is 200 metres enough water resistance?
Comfortably. Recreational diving rarely passes 40 metres, and the rating is a pressure-test figure with a wide margin built in. What matters more in daily life is a screw-down crown, which all three of these have.
HydroConquest or Ocean Star?
The Longines for the ceramic bezel, the thinner case, the silicon hairspring and five years of warranty. The Mido for eighty hours of power reserve and about nine hundred euro left in your pocket. Both are Swatch Group; neither is a mistake.
Which dive watch suits a small wrist?
The HydroConquest 39 (48.1 mm lug to lug) and the Seiko Prospex SPB117J1 at 39.5 mm. The Mido Ocean Star Tribute at 40.5 mm with 21 mm lugs is the third option; the 42.5 mm Ocean Star 200 needs a bigger wrist.
Can I order any of these to the United States?
Yes. The 22% Italian VAT is removed for deliveries outside the European Union, prices convert to dollars, and each product page shows an estimated import duty and a delivered total before you order.
