Special parts are needed to repair the out-of-order landmark clock at Sessions House.

The time showed about 12.30pm when a photographer from The Royal Gazette took a picture just after 1.30pm yesterday.

It is understood the clock has been stopped since at least Monday. A spokeswoman for the Ministry of Public Works said yesterday that the department was aware of the problem and was “awaiting specialised parts which are needed to repair a mechanism”. She added: “The ministry regrets any inconvenience caused to the public.”

The clock suffered similar problems at the end of last year, when the clock was either stopped or running too slow.

Sessions House was built about 1819 and the addition of a clock tower, to commemorate Queen Victoria’s Golden Jubilee, was proposed in 1887.

But work on the project, which also included the red Florentine-style façade, started late and construction was not completed until 1893.
