Buying guide

Which DOXA to buy: every SUB compared, from the 300T to the C-Graph (2026)

DOXA makes nothing but dive watches, and almost all of them are versions of one design: the SUB, with its orange dial and its bezel for timing a dive. Goldsmiths sells six kinds, from the 1,200-metre SUB 300T to a dive chronograph. This is what each one is for, and which to buy.

  9. Questions people ask

The DOXA to buy for most people is the SUB 300T: the least expensive DOXA at Goldsmiths, water resistant to 1,200 metres, in your choice of colour. For the original 1967 shape, the SUB 300; for travel, the 40mm SUB 250T GMT; for a dive chronograph, the SUB 200 C-Graph II.

Every watch here is sold new by Goldsmiths, a UK authorised retailer, at Goldsmiths' own price on the date shown.

How we chose

We went through every DOXA Goldsmiths sells and compared the sizes, water resistance and movements from Goldsmiths' own product pages. Where Goldsmiths' descriptions disagreed (two give different years for the original SUB 300T), we left the detail out rather than guess. We earn a commission if you buy through our links, which never changes the price you pay.

The DOXA range, in short

Goldsmiths' descriptions say DOXA launched the SUB in 1967 as "the first truly purpose-designed diver's watch accessible to a broader public", with an orange dial for reading underwater and a patented one-way bezel showing both dive time and depth. Every DOXA Goldsmiths sells is an automatic dive watch; the differences are size, depth and what the watch does.

Model Size Water resistance What it adds Price
SUB 300T 42.5mm 1,200m Helium release valve £1,890
SUB 300 42.5mm 300m The original shape, COSC chronometer £2,590
SUB 250T GMT 40mm 250m A second time zone £2,390
SUB 200 C-Graph II 42mm 200m Chronograph £2,790
SUB 1500T 45mm 1,500m Deepest, helium release valve £2,390
Army 42.5mm 300m Military-style reissue £2,150

The best value: SUB 300T

The most DOXA for the money. Goldsmiths describes the SUB 300T as a tribute to DOXA's SUB 300T Conquistador, "the first general public diver's watch equipped with a helium release valve", relaunched in September 2019. The modern one has a 42.5mm steel case, a sapphire crystal and Super-LumiNova, and it's water resistant to 1,200 metres. Aquamarine is one of several colours, all at the same price.

The original: SUB 300

The shape DOXA launched in 1967. Goldsmiths lists the Sharkhunter (black) with a 42.5mm steel case 13.4mm thick, a domed sapphire crystal, a COSC-certified chronometer movement with a 38-hour power reserve, and water resistance to 300 metres. It costs about £700 more than the 300T, and goes less deep: you're paying for the original design.

Deciding between these two? Our SUB 300 vs SUB 300T guide goes through every difference.

The best for travel: SUB 250T GMT

A dive watch with a second time zone. Goldsmiths describes the SUB 250T GMT as "DOXA's return to the GMT function": a skeletonised GMT hand tracks a second time zone, in a 40mm steel case, the smallest here, with a screw-down crown and a one-way diving bezel. It's water resistant to 250 metres, with a Swiss automatic movement and a 50-hour power reserve, on DOXA's "beads of rice" steel bracelet with a diving extension.

The best chronograph: SUB 200 C-Graph II

A dive watch with a stopwatch: three counters for timing dives, in a 42mm steel case 15.85mm thick. Goldsmiths' description calls it a "tool watch" for demanding dives, with a sunburst orange dial, a one-way steel bezel and water resistance to 200 metres, and a power reserve of up to 56 hours. It also comes on a rubber strap.

The deepest: SUB 1500T

Built for 1,500 metres. Goldsmiths describes the SUB 1500T as a successor to the SUB 300T Conquistador, with the same patented one-way bezel and a helium release valve, in a 45mm cushion-shaped steel case. It's the largest DOXA here: try one on if you can, or check the size against your wrist with our watch size calculator.

Questions people ask

Which DOXA should I buy first?
For most people, the SUB 300T: it's the least expensive DOXA Goldsmiths sells, about £1,890 when we checked, and water resistant to 1,200 metres. If you want the original 1960s shape instead, the SUB 300 costs about £700 more. Our SUB 300 vs 300T guide compares the two in detail.
What do the DOXA colour names mean?
Each dial colour has its own name. Among the watches Goldsmiths sells, Professional is orange, Sharkhunter is black, and Caribbean and Aquamarine are blues. Versions of the same model in different colours cost the same at Goldsmiths, such as the four SUB 300Ts at about £1,890 when we checked.
Is DOXA a good watch brand?
DOXA is a Swiss brand known for one thing: dive watches. Goldsmiths' descriptions say its SUB of 1967 was the first purpose-designed diver's watch for the general public, with a bezel for both dive time and depth, which DOXA patented. It's a specialist rather than a famous name, so you get serious dive specifications for the money.
Are DOXA watches waterproof?
They're built for diving: water resistant to 200 metres (the C-Graph) up to 1,500 metres (the SUB 1500T), according to Goldsmiths, and every DOXA in this guide is fine for swimming and diving.
How much is a DOXA watch in the UK?
At Goldsmiths, from about £1,890 for the SUB 300T to about £2,800 for the SUB 200 C-Graph II, with carbon and ceramic models above that, when we checked. Each watch in this guide shows Goldsmiths' price, checked every morning.
