Dear staffs from ROGER W SMITH LTD,

My name is Dimitry, and I am a member from the National Association of Watch and Clock Collectors(aka. NAWCC) and a big fanatic of horology.

In the recent years, I have read the masterful books "George Daniels: A Master Watchmaker & His Art" written by Mr. Micheal Clerizo and "All in Good Time: Reflections of a Watchmaker" written by the late great master George Daniels.

After reading the articles regarding the development of the co-axial escapement, I found that the primary objectives for inventing the co-axial escapement are eliminating the use of lubricants on escapement parts and prolonging both the service interval and lifespan of a mechanical movement.

My questions are: Has Mr. Smith achieved all these objectives on the Series 2 movement, his masterpiece? If so, How long would the intended service interval be for a Series 2 movement? (compare to average service interval for average watches in once every 4 to 5 years) and how long is the intended lifespan of a Series 2 watch if the whole watch is being used and maintained properly?( as I learned before, an average 17-jewel, hand-wound movement can last for 200 to 300 years if used and maintained properly)

I am looking forward to receive a satisfactory answer from Mr. Smith.

Sinciere regards,

Dimitry

It was found that modern cleaning methods are ultra effective and the escape wheel teeth were left in such a dry state that an oxide deposit built up at the point of contact with the tooth and the jewel. A tiny amount of lubrication takes the dryness away and prevents this oxide from building up.

With regards to service interval, Roger tells his clients that he is happy for them to run their watches until they stop. This could be in 10, 20 or 30 years – we just don’t know. He bases this thinking on the fact that his watches are low beat (18,000 vibs per hour) and built to a standard which goes way beyond a modern mass produced watch. This design philosophy, when combined with the co-axial escapement which through its design is impervious to the deterioration of an applied lubricant means that a steady rate of timekeeping should also be maintained over this long period.
