Our independent horological showroom at 19 Fore Street, Totnes was established in August 2000. For over a quarter century, we have remained a family-run business dedicated to the South Devon community, merging technical watch expertise with traditional master jewellery craftsmanship and local accountability for our South Hams clientele.
2. Eco-Drive Solar Technology
7. How does a light-powered chronograph charge?
Citizen Eco-Drive Chronograph modules utilize high-sensitivity light panels located behind the dial. These panels convert any natural or artificial light source into electrical energy, which is stored in a long-life rechargeable secondary cell. This sustainable technology ensures the high-torque chronograph hands remain operational without the need for traditional battery changes in our Totnes workshop.
8. How long does a Citizen chronograph battery last?
The high-capacity rechargeable storage cells in Citizen Eco-Drive chronographs are engineered for exceptional longevity, typically maintaining an efficient operational lifecycle for 15 to 20 years. Unlike standard quartz chronographs that require silver-oxide battery changes every 2 years, the Eco-Drive system is a set-and-forget power solution designed for decades of technical reliability.
9. Does the chronograph function drain the battery?
Continuous use of the high-torque stopwatch hands consumes more energy than standard timekeeping. However, the Eco-Drive system is designed to harvest light energy passively. Even with regular chronograph use, standard indoor or outdoor light exposure is sufficient to maintain a full charge, ensuring the module never depletes its secondary power reserve during timing operations.
10. Does indoor light charge a Citizen watch?
Citizen's high-sensitivity photovoltaic cells are calibrated to harvest energy from low-intensity indoor lighting, including fluorescent and LED bulbs. Although natural sunlight is the fastest charging source, standard office or home lighting is sufficient to maintain the cell's energy level, providing a truly sustainable power solution for modern South West professionals.
11. What is the Power Reserve indicator on a chronograph?
Many Citizen chronographs feature a dedicated sub-dial that indicates the current amount of electrical energy stored in the rechargeable cell. This visual gauge alerts you when the watch requires more light exposure (Medium or Low states), ensuring that your timing instrument remains fully operational for professional use at all times.
12. How do I reset my Citizen chronograph?
Reset procedures vary by calibre number. Most Citizen chronographs require a specific 'All-Reset' button hold followed by a manual 'reference position' alignment of the sub-dial hands. Our horological team at 19 Fore Street can demonstrate the correct calibration techniques or perform a full technical reset for you in our physical showroom.
3. Specialised Chronograph Functions
13. What is the 1/5th second chronograph hand?
The 1/5th second resolution indicates that the central sweep chronograph hand moves in five distinct increments per second. This high-frequency movement provides a more granular and precise measurement of elapsed time compared to standard 1-second ticks, allowing for professional-level timing accuracy in aviation and motorsport settings in Devon.
14. What is the tachymeter scale used for?
The tachymeter scale, often found on the outer bezel or internal dial ring of Citizen chronographs, allows the user to calculate speed based on travel time over a fixed distance (such as one mile or kilometre). By starting the stopwatch at the beginning of the distance and stopping it at the end, the central hand points to your average speed.
15. What is a flyback chronograph?
A flyback chronograph is a technical complication that allows the stopwatch to be reset to zero and instantly restarted with a single press of the button. This is particularly useful for pilots and navigators who need to time successive legs of a flight plan without the multi-step stop-reset-start procedure required on standard chronographs.
16. What is a split-time function?
The split-time function allows you to pause the chronograph hands to read an intermediate time while the internal module continues timing in the background. Pressing the button again causes the hands to 'catch up' to the ongoing elapsed time, an essential feature for timing multi-lap events or multiple athletes in athletic settings.
17. Does Citizen offer GMT chronographs?
Yes, several Promaster and World Time models feature an additional 24-hour hand or digital display to track a second time zone alongside the chronograph stopwatch. This dual-time capability is invaluable for international business travellers and pilots who require instant reference to UTC (Greenwich Mean Time) on their analogue dial.
18. What is the benefit of an Auto-Calendar in a chrono?
Integrated auto-calendars in Citizen modules automatically adjust the date display for different month lengths and leap years through to the year 2100. This technical automation ensures your watch always displays the correct date without manual intervention at the end of each month, a standard feature in our Radio-Controlled and GPS chronographs.
4. Materials & Metallurgical Engineering
19. What is Super Titanium used in chronographs?
Super Titanium is Citizen’s proprietary material, created by treating solid titanium with Duratect surface-hardening technology. This results in a case and bracelet that is five times harder than stainless steel and 40% lighter. It offers superior scratch resistance and lightweight comfort, making it the definitive choice for daily professional wear in Devon.
20. Is Super Titanium hypoallergenic?
Yes, Citizen Super Titanium is treated with Duratect surface hardening, which is nickel-free and highly biocompatible. This makes it the safest horological choice for clients with sensitive skin or metal allergies. It is resistant to corrosion from salt water and sweat, ensuring long-term comfort and metallurgical integrity for South Hams residents.
21. What is the benefit of a Sapphire Crystal?
Sapphire crystal is the second hardest material after diamond (9 on the Mohs scale). Premium Citizen chronographs utilize sapphire glass because it is virtually unscratchable, ensuring that the complex dial and sub-dials remain clear and legible even after years of exposure to harsh, abrasive professional environments.
22. Is the sapphire glass anti-reflective?
Yes, premium Citizen chronographs feature anti-reflective (AR) coating on the underside of the sapphire crystal. This technical treatment significantly reduces glare from natural or artificial light, providing exceptional dial legibility in direct sunlight or bright aircraft cockpits, a vital requirement for the Promaster Sky series.
23. What is the weight difference of Super Titanium?
Super Titanium is roughly 40% lighter than standard 316L stainless steel. This significant reduction in mass means that even larger-diameter Promaster chronographs feel incredibly comfortable and almost weightless on the wrist. This technical advantage reduces wrist fatigue for professional pilots and divers during long periods of active deployment.
24. Are your diamonds GIA certified?
Yes, H.E. Phillips Ltd specialises in GIA (Gemological Institute of America) certified diamonds. We ensure that all stones used in our bespoke jewellery and restorations are independently graded for Cut, Colour, Clarity, and Carat weight, providing absolute quality assurance in our Totnes showroom for our Devon clientele.
5. Accuracy & Satellite Calibration
25. What is the accuracy of a Citizen Chronograph?
Standard Citizen Eco-Drive chronographs are accurate to ±15 seconds per month. However, for users seeking the ultimate precision, our Radio-Controlled and Satellite Wave GPS models offer timekeeping accurate to within 1 second per 100,000 years, automatically calibrating daily to the national atomic clock signal or GPS frequency.
26. What is the Radio-Controlled function?
Radio-Controlled technology allows the Citizen watch to receive low-frequency radio signals from atomic clocks globally, including the Anthorn transmitter in Cumbria. This ensure that your watch performs a daily time adjustment to atomic-clock precision, maintaining absolute accuracy to the second without any manual intervention required from the user.
27. What is the Satellite Wave GPS function?
Satellite Wave GPS allows the chronograph to receive time signals from GPS satellites orbiting 20,000km above the Earth. This ensures the watch is calibrated with atomic precision anywhere on the planet in as little as 3 seconds. It automatically adjusts for your current time zone, providing the ultimate timing tool for international explorers.
28. How accurate is the quartz oscillator?
The internal quartz crystal in a Citizen module vibrates at exactly 32,768 Hz. This consistent high-frequency vibration ensures a precision of ±15 seconds per month. This technical stability is why quartz modules became the global standard for reliable and accurate professional timing instruments during the late 20th century.
29. Are Citizen watches magnetic resistant?
Yes, modern Citizen modules feature specialized magnetic-resistant shielding. This technical engineering protects the movement from interference caused by household electronics, smartphones, and medical equipment. This ensures the watch maintains its accuracy even in environments with standard electronic interference common in modern South West homes.
30. What is the Atomic signal range for UK users?
The UK atomic signal is transmitted from Anthorn, Cumbria. This signal covers the entire British Isles, ensuring that your Radio-Controlled Citizen watch receives a strong signal for daily calibration in Totnes and across Devon, maintaining absolute synchronization with the national time standard automatically every night.
6. Water Resistance & Promaster Use
31. Can I wear my Citizen Chronograph for swimming?
Promaster Chronograph models are ISO-rated to 200 metres, making them suitable for professional diving and marine activity. For everyday swimming, models rated to 100m are sufficient. We always recommend ensuring the screw-down crown is fully secured before any submersion to protect the Eco-Drive module from moisture ingress.
32. Can I wear my chronograph in a hot tub?
We strongly recommend removing your chronograph before entering a hot tub or sauna. The combination of high heat and steam can cause the internal air to expand, which may temporarily compromise the integrity of the rubber gaskets. Removing the watch prevents long-term moisture ingress behind the crystal and preserves the life of the seals.
33. What is the lifecycle of a Citizen gasket?
To maintain 200m water resistance, we recommend a technical gasket inspection and pressure test every 2 to 3 years. Rubber seals can become brittle or compressed over time due to age and temperature fluctuations. Our Totnes workshop performs these vital checks during any service to ensure your module remains technically protected.
34. Can hand sanitisers affect my watch?
Occasional contact with hand sanitiser will not harm the stainless steel or titanium case. However, repeated exposure to alcohol-based sanitisers can cause the rubber gaskets to dry out and become brittle, potentially compromising the watch's water resistance. We recommend rinsing your watch in fresh water after frequent contact with chemicals or coastal salt water.
35. What is a depth meter in a Promaster?
Found in Aqualand chronographs, the depth meter sensor automatically measures diving depth and displays the data on the dial. This is a critical safety tool for professional and recreational divers operating in South Devon's coastal waters, providing real-time data alongside standard chronograph timing features for underwater safety.
36. Do you sell Blue Angels chronographs?
Yes, as authorised UK stockists established in August 2000, we maintain inventory of the official Blue Angels collection. These chronographs include the Skyhawk A-T and Nighthawk series, featuring multi-band atomic timekeeping, flight slide-rule bezels, and the official squadron colours, making them highly collectible professional pilot tools.
