Top 6 Affordable Dive Watches

Let’s kick things off with the Seiko Prospex Sumo—a classic dive watch that’s a favourite among enthusiasts. This is a big watch, with a 45mm diameter and 12.9mm thickness, making it perfect for those who like a chunkier piece on their wrist. Seiko has really made a name for itself with the crown placement at 4 o’clock, which gives this watch a unique look.

The Sumo has sapphire crystal and is water-resistant up to 200 meters, perfect for diving or just a day at the beach. Powered by the 6R35 automatic movement, it has a 70-hour power reserve, which is quite impressive for its price point. Overall, the Seiko Prospex Sumo is a fantastic dive watch for under £1,000.

Certina might not get as much love as it deserves, but the Certina DS Action Diver Titanium is seriously underrated. This 38mm beauty is lightweight, thanks to its titanium case, and is a great option for those who prefer something a bit more compact. Despite its smaller size, it’s incredibly durable and perfect for both everyday wear and underwater adventures, with 300m water resistance.

Powered by the Powermatic 80 movement, this watch offers an impressive 80-hour power reserve, which is excellent at this price point. Being part of the Swatch Group, Certina ensures quality, and the Powermatic 80 is a reliable workhorse movement, also used by brands like Tissot. In short, the DS Action Diver gives you a whole lot of watch for your money, and its sleek, dark aesthetic makes it a standout in the dive watch world.

The Citizen Eco-Drive Promaster is another excellent pick, especially for fans of eco-friendly technology. This watch is powered by Citizen’s Eco-Drive movement, which uses light (even artificial light) to keep it charged. That means no more battery replacements—ever.

This watch is on the larger side, with a 44mm diameter and 200m water resistance, so it's designed for water use but functions just as well as a durable everyday option. The stainless steel case and rotating bezel add to its durability, and the green dial version is especially eye-catching. Citizen has been excelling with their Eco-Drive models, and this one is no different—practical, stylish, and reliable.

For those willing to step up in price, the Longines HydroConquest is a fantastic mid-range diver. This watch offers a classic, refined look with plenty of modern features. It’s available in multiple sizes, including 39mm, 41mm, and 43mm, with the 41mm version being the sweet spot for most people.

This watch is powered by the Longines L888 automatic movement, which offers a 72-hour power reserve and beats at 25,200 vibrations per hour. The 200m water resistance makes it a capable dive watch, while the different colour options (including blue, black, and green) allow you to pick one that best suits your style. Longines is known for its heritage and craftsmanship, and the HydroConquest doesn’t disappoint in either department.

Need something with a bit more functionality? The Longines HydroConquest GMT is your go-to. This model features a GMT complication, allowing you to track multiple time zones—perfect for frequent travellers. It’s a bit pricier, but you’re getting a serious tool watch that looks fantastic on the wrist.

At 41mm in diameter and 11.9mm thick, it has all the hallmarks of a great dive watch, including 300m water resistance. The subtle splashes of orange on the dial and the GMT hand add a nice pop of colour. Overall, it’s a versatile and stylish option for those who want a dive watch with added functionality.
