The DOXA SUB 300 Carbon Whitepearl is a white-dial version of the brand’s forged-carbon SUB 300, not a carbon model first introduced in 2026. DOXA says the carbon SUB 300 became available in 2021; its Whitepearl announcement covers several SUB models. The Whitepearl’s defining combination is a 42.50 mm forged-carbon case, a titanium inner chamber and case back, a COSC-certified automatic movement, and 300-meter water resistance.
This is a specification-led look at DOXA’s published information, not a report of independent wear or dive testing. DOXA identifies this version as SKU 822.70.011.23.
What makes the Whitepearl version different?
Whitepearl is a colorway applied to DOXA’s existing SUB range, including the SUB 300 Carbon. DOXA’s press-room statement says the SUB 300 Carbon, SUB 300, SUB 300T, SUB 600T, and SUB 1500T are available in Whitepearl. The announcement does not establish an exact publication date, so it is more accurate to describe this as the Whitepearl execution of the carbon SUB 300 than as a newly launched 2026 watch.

The EU product listing describes the dial as completely coated with white Super-LumiNova. DOXA’s UK listing instead emphasizes luminescent coating on dive-related markings. Those descriptions differ in emphasis; neither listing provides independent measurements of brightness or lume duration. DOXA EU product listing DOXA UK product listing

Case, dimensions and water resistance
The case is forged carbon and measures 42.50 mm in diameter, 45.00 mm long, and 13.40 mm high, according to DOXA. The brand specifies a titanium chamber and a screw-down case back, as well as a screw-down crown. Water resistance is rated at 30 ATM, equivalent to 300 meters or 984 feet. These are manufacturer specifications, not a record of independent testing.
For context when considering fit, the listed 45.00 mm length is the case’s stated length; it is not a measurement of the full watch across the strap. The watch also has a 20.00 mm lug width, which matters when assessing replacement strap compatibility.

Movement, display and timing
DOXA lists a Swiss mechanical, self-winding movement that is COSC-certified as a chronometer. The stated power reserve is 38 hours and the frequency is 28,800 vibrations per hour (4 Hz). DOXA says the movement is decorated by the brand. The display shows hours, minutes, seconds, and date; the UK product description places the date at 3 o’clock.
COSC certification is the manufacturer’s stated movement certification. DOXA’s product pages do not provide independent accuracy results for this particular watch, so certification should not be confused with a published test of its performance after casing or during everyday wear.
