On a previous post i presented a graph about my watches movements performances. One of them was a ZJS Chinese movement that i found, three years ago, inside a fake 'Rene Valentine' mechanical watch. It was forgotten in my father's old stuff for many years ( probably since late 80's ) though it start running again when i winded it.
The watch case condition is very bad and the performance of the movement was very disappointing (+83 sec/day). Though, recently i realized that most of these watch 'engines' features an accelerator! So i decided to take this 'old Chinese gentleman' for a ride...
Over the balance wheel of the movement there was marks ( + - ) and two adjustment arms isochronism and regulator. It's strongly recommended to Not move the isochronism arm and only adjust the regulator in + or - direction. This will speedup or slowdown the watch!
These arms are very sensitive and at the beginning of my adjustments the watch got 'crazy'. I was manually...
The Magic Powers of Mechanical Movement (10 steps)
One of the mysteries of all times, is time it's self. Not only exists in present but also through the past and to the future.
Time: A component quantity of various measurements used to sequence events, to compare the duration of events and to quantify rates in material reality or the conscious experience.
The indefinite continued progress of existence. Time is often referred to as a fourth dimension.
Timepiece is an instrument used to measure, keep, and indicate time. One of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units: the day, the lunar month, and the year. A mechanical watch is a timepiece that uses a clockwork mechanism to measure the passage of time.
Mainspring is a spiral flexible, elastic metal ribbon that stores mechanical energy when it is twisted.
A mechanical watch is driven by a mainspring which must be wound either periodically by hand or via an automatic winding mechanism.
Humans have long been fascinated by horology, or the study of timekeeping. And it’s not just the mechanisms themselves that have captivated us—it’s the idea of measuring an intangible.
Beyond watches themselves, what is it about horology that interests you? Why have we as humans been obsessed with the concept of time since, well, the dawn of time? Are there certain moments in horological history that you’re particularly fascinated by?
The iconic Zenith El Primero caliber 3019 PHC manually-wound movement
Hey all, I wanted to start a new series! Obviously, many people here are already extremely knowledgeable about watches, but one of the joys of the hobby is spreading knowledge. Please let me know in comments if there's anything that the community would like to learn about. I definitely don't know everything (or even more than many people), but we have such a breadth of knowledge in the community that it would be a waste to not share! For this first installment, I'd like to talk about the (almost literal) heart and soul of every watch, the movement.
WHAT IS A MOVEMENT?
The movement of a watch refers to all of the internal workings that keep it running and telling the time. The movement includes, but is not limited to, components that store power to drive the rest of the movement, gears that turn the hands and run the complications, jewels/screws/plates that hold the whole thing together, etc.
Recently purchased a zippered travel case designed to accommodate three reasonably-sized dive watches--or so I thought. In practice I discovered the diameter of the supplied inserts were far too narrow to properly secure any of the bracelets on my watches--that left them all loose and floating around in the case with nothing to prevent them from banging into one another--not exactly what I was hoping for!
Solution: I purchased one of those kid's swim-noodle-floats and sliced off three custom-fit inserts. The floats come in assorted diameters and I was able to find one that was just a tad larger than my average adjusted bracelet size. The foam compresses slightly as each bracelet clasp is snapped shut, leaving everything nice and tight and well-secured from movement in the case--no more shake, rattle and roll!
The too-small grey inserts as supplied, and the orange slices I cut from a five-foot swim float.
The foam is very easy to cut with a kitchen knife. I'll probably...
What are the usual techniques to check if a timepiece is a duplicate/fake by yourself ?
I recently bought my timepiece from an online retailer(not authorized by watchmaker). I went ahead and bought the watch as its a well-known online website. I did do my research on the model number before making the purchase. I called the watchmaker and checked with them if the model number is genuine and not a fake. After a chat with the customer-care of the watchmaker, they told me that this model was discontinued and they could not confirm when the watch was discontinued, and they did not guarantee the authenticity of the watch if it was bought from any other seller other than mentioned on the watchmaker's online retailer list.
So I would like to ask as a buyer, what should you be checking once you receive the timepiece; for the authenticity of the watch(other than taking it to the watchmaker's service center or taking it to a 3rd party watch service center)
I have added the pictures of my...
