Citizen Promaster WaveTracker JV3006-50L Watch
The Citizen Promaster WaveTracker JV3006-50L is a regatta watch with a high-definition MIP LCD display, a 42.4 mm stainless steel case and a matching bracelet. Its U812 calibre runs on Eco-Drive, meaning it charges from any light source and never needs a battery. The dot-matrix screen shows the regatta timer, the tide graph for over 200 locations and the sunrise and sunset times for as many destinations. It is not a smartwatch: it is a navigation tool that works without apps and without a charger.
The case is 13.9 mm thick and weighs 180 g. The crystal is anti-reflective sapphire, the crown and case back are screw-down, and water resistance is 20 bar (200 metres). The bezel is unidirectional, designed for measuring regatta times. The steel bracelet has 22 mm between lugs and a deployant clasp with safety pusher. The dial combines luminous hands with the digital screen, which can be set to positive or negative.
The U812 calibre integrates the functions of a nautical instrument: regatta timer with countdown and automatic chronograph start at zero, tide graph for over 200 locations, sunrise and sunset times, world time for 43 cities, chronograph, alarm, perpetual calendar, moon phase indicator and low charge warning. The MIP display reads clearly in direct sunlight, something not all digital screens achieve.
The regatta timer on this WaveTracker is not just another function: it is the reason a sailor chooses this watch over a conventional chronograph. When you are on the start line and the five-minute signal sounds, you don't have to calculate the remaining time in your head: the screen shows the countdown and, at zero, automatically starts the chronograph. The tide graph tells you when the water rises and falls at the location you have selected. And it all works without a battery, because Eco-Drive charges from sunlight or cabin light. It is the gesture of the navigator who carries the instrumentation on the wrist, not on the boat's panel.
Eco-Drive MIP Display Regatta Timer Tide Graph Sapphire 200 m 42.4 mm 180 g
Why choose this watch?
MIP display: the navigation tool that doesn't need a battery
The MIP dot-matrix screen reads in direct sunlight and shows the regatta timer, tides and world time without relying on a smartphone. It is the difference between a conventional digital watch and a navigation instrument.
Regatta timer with automatic chronograph start
The countdown is set for 5 or 10 minutes and, at zero, the chronograph starts on its own. It is the function a sailor uses on the start line, and it requires no mental calculation.
Tide graph for over 200 locations
The watch shows the high and low tide for the location you select, with the exact time. It is useful for planning a trip on the water, a crossing or a day's fishing, without checking another app.
Eco-Drive and 200 m: no battery and no worries
The U812 calibre charges from light and needs no battery. The 200-metre water resistance and screw-down crown cover nautical and sports use. It is a tool that won't let you down for lack of power.
42.4 mm and 180 g: instrument presence
The steel case and bracelet give it a weight you feel on the wrist. It is not a discreet watch: it is an instrument with volume, designed for navigation and intensive use.

Frequently asked questions
What is the regatta timer and what is it for?
It is a countdown designed for regatta starts. It is set for 5 or 10 minutes, and when it reaches zero the chronograph starts automatically. This way the sailor knows exactly when to cross the start line without having to calculate the remaining time from memory.
Does the MIP display read well in sunlight?
Yes. MIP (Memory in Pixel) technology is designed to maintain contrast in bright light, something not all digital screens achieve. It can be set to positive or negative according to user preference.
Is the bezel unidirectional or bidirectional?
It is unidirectional. It is designed to measure regatta times and prevent an accidental turn from lengthening the measurement. It is the same type of bezel used on dive watches to measure immersion times.
Can the steel bracelet be changed for a rubber strap?
Yes. The bracelet is mounted with standard 22 mm pins, so it can be changed for a rubber or other material strap without special tools beyond a strap-changing tool. Citizen sells the rubber strap version under reference JV3000-13E.
What is the difference with the rubber strap WaveTracker?
The main difference is the bracelet: steel on this JV3006-50L and rubber on the JV3000-13E. The movement, display, functions and case are the same. The steel one has a more classic nautical instrument look; the rubber one is more sporty and lighter.
