I recently used
marrickville here in Sydney to service a Noob Omega CrPO with Asian 2836-2 clone. Marrickville's service was great at all levels:
* clear, prompt and frequent communications including images of the work in progress and issues found
* able to start the work quickly
* fast turn-a-round of 1 week and that included several days of monitoring the movement's performance after rebuild
* excellent workmanship; no scratches anywhere, no dust in dial, everything immaculate
* the movement had some challenging issues which marrickville dealt with by replacing damaged parts with parts held in stock (no delay)
* work came with a 12 month warranty
Overall I couldn't be happier with the marrickville's work. Highly recommended professional watchsmith based in Sydney.
