4. Why buy from an independent specialist in Devon?
Independent specialists provide immediate hands-on calibration, custom physical bracelet adjustment, and face-to-face workshop support that national drop-shipping networks cannot provide.
2. Movement & Mechanical Logic
5. What movement is in the GB02940-06?
The timepiece operates via a self-winding automatic mechanical calibre, which uses an oscillating rotor weight to generate power from normal physical arm motion.
6. Does this watch require a battery?
No, this model does not utilize electronic circuits or quartz cells; it relies entirely on a tensioned mainspring to distribute kinetic power through the wheel train.
7. What is the power reserve of the Greenwich?
The internal mainspring assembly stores an approximate 42-hour power reserve, meaning the watch will continue ticking overnight when off the wrist.
8. How accurate is the automatic calibre?
This movement holds a standard daily operational window of -20 to +40 seconds per day, which represents the typical benchmark for fine non-COSC mechanical calibres.
3. Materials & Metallurgy
9. What grade of stainless steel is the case?
The entire watch chassis and link assembly are engineered using premium 316L surgical stainless steel, chosen for its excellent defense against pitting and acid corrosion.
10. What is the specific gravity of the 316L steel?
The specific gravity of 316L alloy measures at 8.00 g/cm³, giving the watch body a reliable, heavy weight profile that denotes structural density on the wrist.
11. Is the case hypoallergenic for sensitive skin?
Yes, the structural composition of 316L alloy isolates nickel elements, making it safe for long-term daily wear on sensitive skin in line with UK REACH metrics.
12. What is the Vickers Hardness of the polished case?
The treated 316L case surfaces display a mechanical hardness rating between 200 and 240 HV, ensuring security against standard surface abrasions.
4. Crystal & Dial Features
13. What glass crystal is used on the Greenwich?
The front window is built with highly resilient, scratch-resistant synthetic Sapphire crystal to maintain visual transparency over decades of ownership.
14. How hard is sapphire glass technically?
Sapphire crystal registers at 2200 to 2300 HV on the Vickers scale (Mohs 9), indicating that only diamond or specialized industrial compounds can scratch it.
15. What is a skeletonized dial?
A skeletonized format involves precision cutting away of the dial surface and main plates, exposing the balance wheel, hairspring, and gears to direct view.
16. Are the indices applied or painted?
The GB02940-06 model utilizes individual applied silver-tone hour markers, fixed directly over the open framework to optimize dark legibility and contrast.
5. Water Resistance & Aftercare
17. Is the Greenwich GB02940-06 waterproof?
The watch is safety sealed to 5 ATM (50 metres), protecting the mechanical movement from rainfall, handwashing, and incidental exposure, but is not built for immersion.
18. What does 50m water resistance technically mean?
It states that the case structure can resist a static pressure environment equal to 5 atmospheres, rather than a dynamic depth recommendation for diving activities.
19. How often should an automatic watch be serviced?
We recommend undergoing an internal overhaul, oil replenishment, and gasket replacement cycle every 3 to 5 years to preserve accurate timing output.
20. Can you repair Rotary watches locally?
Yes, our independent workshop team at 19 Fore Street provides comprehensive local servicing, calibration testing, and full technical maintenance for Rotary watches.
