Synthesizer shopping in Tokyo

Japan is a powerhouse in synthesizer manufacturing and I expected on a recent trip
to Tokyo to be swamped with shops selling all manner of keyboards.
However, they are not as common as one might expect.

Below are the ones I found. Please email me if you know of more.
The largest three are 5G in Shibuya-Ku and Echigoya & Ishibasi in central Shibuya.
Ochanomizu is the home of numerous guitar shops. I found two along the main street,
Kanda Surugadai that also sold synthesizers.

IWC Ingenieur - Calibre 852 + 8200 family

 ........................

The IWC Ingenieur was introduced in 1955 as a technical and anti-magnetic tool watch built for engineers, scientists, and technicians working around strong magnetic fields. You can explore the lineup directly on the IWC Schaffhausen Introduction to Ingenieur Watches. [1, 2, 3, 4]

First Generation (1955–1967)

Reference 666: The debut model featured a clean, classic round dress-watch aesthetic with a 36.5mm stainless steel case. [1]
Soft-Iron Cage: It housed an inner soft-iron Faraday cage and dial back that protected the movement from magnetic fields up to 1,000 gauss (80,000 A/m). [1, 2]
Pellaton Winding: It was powered by IWC's first in-house developed automatic movement utilizing the high-efficiency Pellaton winding system. [1, 2]

The Gérald Genta Revolution (1976)

Ingenieur SL (Ref. 1832): In the 1970s, IWC hired legendary designer Gérald Genta—who also styled the Audemars Piguet Royal Oak and Patek Philippe Nautilus—to redesign the line into an integrated luxury steel sports watch. [1, 2]
Design Features: Launched in 1976, the "Jumbo" model featured a 40mm case, a screwed-down round bezel with five functional recesses, a textured "graph paper" dial, and an integrated H-link steel bracelet. [1, 2, 3]
Commercial Legacy: Though initially slow to sell due to its avant-garde look (with just over 1,000 units produced), the SL design became a cult classic and the enduring visual blueprint for the collection. Detailed background on the designer's vision can be found via IWC Gérald Genta Special Feature. [1, 2]

Later Evolution and Modern Era (1980s–Present)

High-Magnetic Milestones: IWC continued pushing anti-magnetic limits, including the Ref. 3508 in 1989 and specialized high-gauss variants. [1, 2]
Collaborations and Variations: The 2000s brought titanium and stainless steel Mercedes-AMG performance editions, followed by complications like the Constant Force Tourbillon in 2013. [1]
Return to Roots: IWC returned to a classic round case shape in 2017, while contemporary iterations continue to honor Genta's 1976 SL geometry with modern mechanics and extended power reserves.

The Pellaton winding movement 

The IWC Ingenieur movement features the Pellaton winding system, a high-efficiency, bidirectional pawl-winding mechanism originally developed by IWC Technical Director Albert Pellaton in 1950 and first introduced to the Ingenieur line in 1955 (such as the Calibre 852). [1, 2, 3, 4]

How the Pellaton System Works

Bidirectional Winding: Unlike traditional automatic rotors that wind the mainspring in only one direction, the Pellaton system captures energy from the rotor as it swings both clockwise and counterclockwise. [1, 2]
Cam and Pawls: An eccentric cam converts the rotational movement of the rotor into a rocking motion. A pair of jewel or ceramic pawls (clicks) mounted on a rocking bridge alternately push and pull the ratchet wheel to wind the mainspring. [1, 2]
Ceramic Upgrades: Modern versions—such as the IWC-manufactured 82000 calibre family used in contemporary Ingenieur models—replace high-friction metal parts with virtually wear-free zirconium oxide ceramic components for the pawls and automatic wheel. [1]

Key Specifications of Modern Ingenieur Movements (e.g., Calibre 82000 Family)

Power Reserve: Offers a long power reserve of 60 to 80 hours (such as 80 hours in variants like the Calibre 82905). [1, 2]
Frequency: Operates at 4 Hz (28,800 vibrations per hour) for smooth timekeeping. [1]
Antimagnetic Protection: Historically and currently paired with a soft-iron inner case to shield the movement from magnetic interference, a defining trait of the scientific and engineer-focused Ingenieur heritage
