High-quality wood created through a collaboration between Japan's leading furniture manufacturer "Tendo" and our watch accessory brand "Accurate Form" watch case. After about a year of planning and repeated prototyping, we were finally able to create a product that we were satisfied with. This product has two types of specifications. One is the " Watch & Jewelry Case " and the other is the specially designed "A-MAG Watch Case" with magnetic shielding performance. There are two types of trees and two sizes: regular and large.
This is the "A-MAG Watch Case" page.

■Development history
There are many electronic devices around us that generate strong magnetism, such as computers and mobile phones. Vintage watches have little protection against magnetic forces. If a watch becomes magnetized, it may no longer keep accurate time and repairs may be costly and time consuming. Dealers and advanced collectors may carry a large number of watches in their bags, along with their computers and cell phones. At that time, we heard many requests for a case that would protect their watches from magnetism and shock, and in order to meet those requests, we decided to develop a watch case with a magnetic shield function. In addition, for those who do not need such specifications, we have also produced watch and jewelry cases that do not have magnetic shielding properties to keep costs down.

・Watch case with magnetic shielding performance
Magnetic A special shield alloy is pasted on the inside to block the magnetic force generated by computers and mobile phones. Although it is not visible visually, the sides of the case (underneath the surface material) are also processed.

・Luxury wooden exterior
As this is a case for storing luxury goods, we believe that a sense of luxury is essential, and we use veneers of precious wood to match the wood grain. I was particular about it. We have prepared Claro walnut and Sapele curly wood, both of which have distinctive wood grains. The surface is coated with drip-proof matte oil to prevent water from seeing in as much as possible.

Regular size (L: Claro walnut, R: Sapele curled heather )

Large size (L: Claro walnut, R: Sapele curled heather)

・Details with a vintage feel
We used materials with a vintage feel for the latches and hinges, and used brass flathead screws.

・Easy to carry
In pursuit of ease of carrying, we have reduced the weight to the extent that durability is not affected. In addition, the corners are rounded to prevent scratches as much as possible. The optimal hardness of the urethane inside is selected from several types, and the suede-like fabric has friction to prevent the watch from slipping while being carried. Comes with an elastic cloth cover to prevent the case from being scratched inside the bag or from opening accidentally. The large case also comes with a heavy canvas tote bag. It is sized to fit two large size pieces. *Regular size does not include tote bag.

□Heavy canvas tote bag (only large size is included)
*As a general rule, you cannot choose the color. If we have it in stock, we will send you your desired color, so please let us know your preference.

・Ideal for indoor storage
The design allows for stacking, so even those who own many watches can store them compactly. It can also be stored vertically, so you can store it on a bookshelf, etc.

・Can also be used as a tray
The upper and lower lids have the same thickness, so when opened, it can be used as a high-quality tray. The urethane inside is covered with suede-like fabric. Convenient for business negotiations and offline meetings.

・Store your watch neatly
You can neatly store your watch. Please refer to the image for the maximum number of watches that can be stored (for watches with an average diameter of 38 mm). Please note that if you store more watches than this, it will put a strain on the case and the metal fittings may break.

■Leather pad (accessory)
This case uses urethane inside to prevent the watch from slipping. Pressure is applied from the top and bottom, so by sandwiching this pad in between, you can prevent scratches on the back cover of bracelet types and marks on the back cover of leather strap when folding leather strap types. Masu. The leather is made from Charles F. Stead's high quality suede.

■ Penetrating magnetic force test
We performed a penetrating magnetic force test using a powerful magnet that generates a slightly stronger magnetic force than a typical PC or mobile phone.
Magnetic force becomes weaker as the distance increases. It is said that the magnetic force of general electrical appliances has almost no effect as long as they are separated by 10 cm or more. In this measurement, we took it at a position 2 cm away from the strong magnet.
*Numbers may vary slightly for each measurement.

・Use equipment that measures electromagnetic waves (above the display) and magnetic force (below the display)
*VPP mode to measure the maximum value
*Unit: mG (milligauss)

□Measurement with "Watch & Jewelry Case" (no magnetic shielding performance)
It can be said that the magnetic force almost penetrates through it. Even if you insert a mobile phone, which has a relatively weak magnetic force, into the cell phone and measure it, the magnetic force will still penetrate.

□ Measurement with "A-MAG Watch Case (ANTI-MAGNETIC Watch Case)" (with magnetic shielding performance)
Several test results The measured value was 0.
