This replica submariner 63443 equips the 116610LN with a diamond-set bezel accented by blue luminous markers, blending the sparkle of pave stones with the cool tones of blue indices around the perimeter. The 40mm case holds the same dimensions as every pre-2020 Submariner, and the overall silhouette remains unmistakable despite the aftermarket diamond treatment. Blue markers against a diamond field give this variant a nautical quality that aligns well with the Submariner’s identity as a diver’s instrument, even in iced-out form.

Build Details

• Case diameter: 40mm
• Reference: 116610LN
• Bezel: diamond-set with blue luminous markers
• Crystal: sapphire with Cyclops lens
• Crown: screw-down with crown guards
• Bracelet: Oyster with folding clasp

The blue markers maintain their glow in low-light conditions, which means the bezel retains partial elapsed-time readability after dark. That functional retention separates this build from fully paved versions where the bezel becomes purely decorative.

What Collectors Notice

Blue accent elements on a Submariner call back to references like the 116619LB “Smurf” and the older 16613 two-tone with blue dial. Using blue markers on a diamond bezel creates a visual bridge between the stone setting and the Submariner’s dive heritage. The rest of the 116610LN package stays conventional: black dial, luminous hour markers, date at three, and the Oyster bracelet with its distinctive flat three-link profile. For a non-diamond alternative with blue emphasis, the Submariner with blue dial SRL50 delivers blue through the dial rather than the bezel. Both belong to the Submariner family, offering different strategies for incorporating blue into the design.

This vs Other Versions

Within the iced-out Submariner range, marker color is the primary differentiator. Green markers lean sporty, white markers stay neutral, and blue markers introduce a cooler, slightly more refined tone. The diamond field amplifies whichever accent color sits within it, so the blue here reads brighter and more vivid than blue markers would on a standard ceramic bezel. If you are drawn to blue-accented dive watches but want the added dimension of diamond pave, this replica submariner 63443 hits that specific intersection without compromising the fundamental Submariner shape.
