MKS 15710 Kizumi Watchmaker's Loupe No. 3.0 (approx. 4.4x) – Eyeglass Loupe for Overview and Case Work | Meikosha, Made in Japan

Original watchmaker's tool from MKS (Meikosha) from Nagoya, imported directly from Japan – not regularly available in Europe.

The Kizumi (キズミ) is the classic Japanese watchmaker's loupe, designed to be held in the eye – the first tool every Japanese watchmaker reaches for. The MKS 15710 is the standard Kizumi in Japanese workshops: a lightweight, matte black body that sits securely and comfortably in the eye socket, with a cleanly ground lens free of edge distortion.

The No. 3.0 is the general-purpose magnification in the series (approx. 4.4x; the number, according to old watchmaking tradition, indicates the focal length in inches – the smaller the number, the stronger the magnification). Its greater working distance and wide field of view make it the ideal loupe for inspecting cases and dials, assessing condition during buying and selling, working on watch bands, and all work "on the entire watch" – it is also the most comfortable magnification for beginners, as it provides more space for the eye and hand. For collectors, it is the classic inspection loupe: assess dials, hands, and case edges at a glance.

What distinguishes this tool from European counterparts:

Functionally, the Kizumi is comparable to well-known Swiss eyepiece loupes (Bergeon 4422 and similar) – the difference lies in fit and weight: the Japanese design is shallower and sits much more securely on many face shapes without a retaining wire or eye strain. In Japan, the Kizumi is part of the official tool lists for the state watchmaker's examination; the MKS version is the common professional quality there. Anyone who has ever worked with a poorly fitting loupe knows: the fit determines fatigue-free work.

The series includes three magnifications: No. 2.0 (approx. 6.0x), No. 2.5 (approx. 5.0x), and No. 3.0 (approx. 4.4x, this offer) – all available individually in our shop.
