Reefline 1 of 1 — Maze No. 01
One of one. The piece that opened the series. No. 01 is where the Artist Series starts: the first dial Mazetheartist painted, the morning the five-piece run began. One of one. The artwork exists on this watch and nowhere else, framed by a black ceramic bezel insert. 316L stainless steel, sapphire crystal, Seiko NH35 automatic underneath the paint.

Reefline Classic — Silverline
One alloy, one dial, no color to hide behind. Silverline is the monochrome standout of the Reefline Classic Series. The silver sunburst dial shifts from soft steel tones to bright highlights as the wrist moves, framed by a black ceramic bezel insert for contrast and lasting scratch resistance. Marine-grade 316L stainless steel, sapphire crystal, and a Seiko NH35 automatic underneath. Specifications Series: Reefline Classic Case material: 316L stainless steel Bracelet: 316L stainless steel, Jubilee or Oyster Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Bezel: Black ceramic bezel insert Dial: Silver sunburst Lume: Swiss Super-LumiNova 10% of every Reefline sale supports the Coral Reef Alliance.

Reefline 1 of 1 — Maze No. 03
One of one. The first to wear blue carbon fiber. No. 03 marks the turn in the series: the first piece to trade black ceramic for a blue carbon fiber bezel insert, a woven ring under the hand-painted dial. One of one by Mazetheartist. The weave reads solid at a glance, then sharpens to a tight twill at arm's length. 316L stainless steel, sapphire crystal, Seiko NH35 automatic. Specifications Series: Reefline Artist Series Edition: 1 of 1, five unique pieces total Case material: 316L stainless steel Bracelet: 316L stainless steel, Jubilee Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Bezel: Blue carbon fiber bezel insert Dial: Hand-painted, one of one, by Mazetheartist Lume: Blue Super-LumiNova 10% of every Reefline sale supports the Coral Reef Alliance.

Reefline Heritage — Deepwater Teal
Solid bronze over a dial the color of deep water. The darker of the two Heritage bronzes. The solid bronze case takes on real patina, from salt, sun and a wrist that lives outside, while the deep teal sunburst pulls deeper as the metal warms, so no two end up alike. Underneath the character: sapphire crystal, Swiss green Super-LumiNova, a Seiko NH35 automatic, and 200 meters of water resistance. Specifications Series: Reefline Heritage Case material: Solid bronze, patinas naturally over time Bezel: Bronze, integrated Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Dial: Deep teal sunburst Lume: Swiss green Super-LumiNova Strap: Vegetable-tanned leather, brushed buckle 10% of every Reefline sale supports the Coral Reef Alliance.

Reefline 1 of 1 — Maze No. 04
One of one. Blue ceramic against hand-laid paint. No. 04 swaps the carbon weave for blue ceramic, a smoother, colder ring that makes the hand-painted dial work harder for the eye, and it does. One of one in the five-piece Artist Series by Mazetheartist. The artwork is never repeated, never re-painted. 316L stainless steel, sapphire crystal, Seiko NH35 automatic. Specifications Series: Reefline Artist Series Edition: 1 of 1, five unique pieces total Case material: 316L stainless steel Bracelet: 316L stainless steel, Jubilee Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Bezel: Blue ceramic bezel insert Dial: Hand-painted, one of one, by Mazetheartist Lume: Blue Super-LumiNova 10% of every Reefline sale supports the Coral Reef Alliance.

Reefline
Reefline Heritage — Emerald Tide
The daylight side of the Heritage bronze. The brighter of the two Heritage bronzes, closer to sea glass than to ocean depth, with an emerald sunburst that pulls almost gold at the edges in midday light. The solid bronze case patinas the same way Deepwater Teal's does: real oxidation, one wrist at a time. Sapphire crystal, Swiss green Super-LumiNova, Seiko NH35 automatic, 200 meters of water resistance. Specifications Series: Reefline Heritage Case material: Solid bronze, patinas naturally over time Bezel: Bronze, integrated Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Dial: Emerald sunburst Lume: Swiss green Super-LumiNova Strap: Vegetable-tanned leather, brushed buckle 10% of every Reefline sale supports the Coral Reef Alliance.

Reefline 1 of 1 — Maze No. 02
One of one. Painted the day after No. 01. No. 02 is the answer to No. 01, painted the following day: the same idea run in a different direction while the first dial was still drying on the bench. One of one in the five-piece Artist Series by Mazetheartist, with a black ceramic bezel insert framing the work. 316L stainless steel, sapphire crystal, Seiko NH35 automatic. Specifications Series: Reefline Artist Series Edition: 1 of 1, five unique pieces total Case material: 316L stainless steel Bracelet: 316L stainless steel, Oyster Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Bezel: Black ceramic bezel insert Dial: Hand-painted, one of one, by Mazetheartist Lume: Blue Super-LumiNova 10% of every Reefline sale supports the Coral Reef Alliance.

Reefline Night Dive — Purple
Stealth black steel, bruise-purple at the rim. Night Dive Purple is the darker end of the pair: black at the center of the dial, bruise-purple at the edge, the sky ten minutes after sundown. The 316L stainless steel case is finished stealth black and brushed flat, so it throws no reflection off the wrist on a night descent. Ceramic bezel insert, Seiko NH35 automatic, screw-down crown, 200 meters of water resistance. Specifications Series: Reefline Night Dive Case material: Black 316L stainless steel Band: Rubber, Jubilee or Oyster Crystal: Sapphire crystal Movement: Seiko NH35 automatic Water resistance: 200M / 660ft Bezel: Ceramic bezel insert Dial: Black-to-purple gradient sunburst Crown: Screw-down Clasp: Micro-adjustment clasp 10% of every Reefline sale supports the Coral Reef Alliance.
