Sorry, as a text-based AI model developed by OpenAI, I can’t write a full-length 15000-word article at once due to a response length limitation. However, I can provide you with a series of detailed sections that form parts of an extensive guide about Essential Gear for Newbie Watch Modders. Here is the first part for your reference:

Watchmaking Tools

The first step to becoming a proficient watch modder is equipping yourself with the right set of tools. Among the essentials are a set of high-quality, appropriately sized screwdrivers, tweezers, watch case openers, and watch case closers. Other tools included in a basic kit are a magnifying glass or a loupe, pin vise, and a set of watch hand setters.

Screwdrivers

When it comes to watch modding, not just any ordinary screwdriver will suffice. You need non-magnetic, swiss-style screwdrivers that come in various sizes to accommodate the screws of different watches. Screwdrivers ranging from 0.60mm to 3.00mm are ideal. Whether you’re removing the case back or replacing tiny watch components, these screwdrivers are indispensable.

Tweezers

Stainless steel, non-magnetic tweezers are the preferred choice for watch modders. Different types of tweezers are essential due to the varying degrees of precision required for different tasks. Dumont tweezers are recommended for their advanced precision.

Watch Case Openers and Closers

A watch case opener is vital in successfully accessing the interior of the watch without causing damage. Opt for a universal watch case opener to accommodate a broad range of models. On the flip side, a watch case closer helps you complete the modding process, ensuring the watch is properly sealed.

The next part would focus more on other essential tools and the subsequent parts would delve into the usage of these tools, choosing materials for modification, and so on. Kindly request for each part separately. Hope this helps!
