Here such hours I bought today. Hours were ordered by party to 1000 pieces for employees of "Tax police" - Federal service of tax police of the Russian Federation (FSNP of Russia) — the law enforcement agency of Russia existing from 1992 to 2003 and was engaged in disclosure of economic crimes. Here about about this service it is detailed http://en.wikipedia.org/wiki/Federal_Tax…sian_Federation
When I bought them they spoiled hour glass a clockwork head is erased, the employee of tax police carried them without removing . As you can see I replaced glass and clockwork heads on new as carried out preventive maintenance of the mechanism, now a course of hours the exact.
