Perhaps it can be said that looking deeper at what you have at your disposal (however limited) and figuring out ways to work with it is even more creative than having unlimited resources and access to machines, factories, and funds.

While the caliber may not be in-house, that doesn't mean the modification isn't, even if it's something as (seemingly) simple as reworking some markers on a disc.

For myself, when designing a watch, adopting this mindset has been the best way to get past any discouraging limitations such as the improbability of creating an in-house movement from scratch or difficulties in finding accessible component manufacturers who are willing and capable.

Movement producers are only responsible for presenting the basics of the caliber. It is up to you to have a broader vision of what is possible - deploying a combination of calculations and creativity.

Oftentimes, this means developing or ordering custom parts to turn the idea into reality.

It is a reminder, particularly to designers, not to be constrained to the off-the-shelf intention of a movement, and to look beyond how the movement is presented in the manufacturer's marketing.

A difference in printing on the calendar discs changes the aesthetics of the dial.

Note: I haven't disassembled each module to confirm technical differences, but this example is used as a graphic explainer to show how different results can be achieved visually without making changes mechanically.

Sometimes, watchmaking is as visual as it is mechanical. For example, look at the Dubois DΓ©praz module DD9000 side-by-side with the DD90000...

Two Seiko watches: One costs a few hundred, the other costs a few thousand... but I think both are grand

I was fortunate enough to meet up with Moritz Grossmann to discuss this caliber and their beautiful watches years ago in Switzerland when I took this pic πŸ€—

"German Silver" in Watch and Watch Movements German silver is another term for nickel silver. Some watch manufacturers use German silver as a more luxurious option for mainplates and bridges. German silver is harder than brass and offers a disti...

From the yellowish tone and clear jewels, you might be thinking the white balance setting on the camera was messed up... but that's just MG's signature look, thanks to untreated German steel and actually clear jewels.

Social media, Bluesky included, is just like everything else... millionaires (in followers and views) get all the opportunities and reach. While we all work to keep the app going.

But it doesn't have to become a parts watch! It is still salvageable with just the center case assembly and an 18mm nylon strap. It actually looks kinda cool. (PS - The pushers won't stick out that far when it's done, I still have to put the e-clips back on each one).

Decided to install a battery and get it back in action, until the outer plastic case (technically called the resin bezel) cracked in half and crumbled to pieces...

Are G-Shocks indestructible or self-destructing? This watch was in a service bag in the repair bin, untouched for the past 10+ years...

Snow day! Let's work on this one...

Girard-Perregaux caliber 170 with major water damage from entry via the crown. The rotor was stuck in position due to layers of corrosion buildup.

From Seiko Museum: "1997 - The Arctura was designed by the internationally renowned watch designer Jorg Hysek and launched as a strategic model for globally marketing Kinetic. The Kinetic, generated its own electricity from the motion of its arms, eliminating the need for battery replacement."
