This website is a journal of my journey in the field of watch repairing, restoration, watch collecting and general watch 'observation'. I hope you will find some of the information provided here educational and entertaining.

Rolex Case Polishing

Restoring or refinishing a stainless steel watch case is not as difficult as may be thought. Unfortunately most watchmakers are either not interested in doing it properly or were never taught how to do it. Those few who have mastered the skill of hand-polishing would rather die then to revel their secret of the trade! The trick in obtaining mirror-like finish is simple ... more

Omega Railmaster 2503.52 Vs. Rolex Explorer 114270

The original Omega Rialmaster was first launched in 1957. as the successor to a watch created for the British Air Force in 1953.

Created in 1953, the Rolex Explorer was intended for rugged expedition use. It was issued for use on many notable expeditions - including the one led by Sir John Hunt which successfully ascended Mount Everest in May 1953...more

Ten things to look for when buying a Rolex watch

How many jewels are inside Rolex Cal. 3135 ?

While doing a bit of research on jewels, I've decided - for the first time ever- to actually count the number of jewels in Rolex Cal. 3135. To my surprise, the total count is 40 - not 31 as marked on the auto bridge. Obviously there has to be a reason behind this ... more

One frustrating restoration project

A very frustrating, yet rewarding restoration project - and on "difficulty scale" this one was solid 8 out of 10. 1880s French carriage clock, quarter repeater that came in in bits and pieces. It took me 2 months to identify what was missing and then to hand make parts, including wheel and pinion cutting...more

DIY: Rolex bezel inserter tool

Totally biased review of an Anonimo Chrono Ref.2007(MCA)
