商品説明
This is a Citizen Super Ace manufactured in 1963 (Showa 38).
The Citizen Super Ace is a high-grade model that inherited the design philosophy of the best-selling "Deluxe" of its time, while aiming for even higher precision and a greater number of jewels (23 jewels).
■ Rare specifications featuring a large 38mm case
The greatest appeal of this watch lies in its adoption of a large 38mm diameter case (actual size approx. 37.8mm), which is unusual for a vintage watch. This design, which is a size larger than the mainstream of its time (33-35mm) and features thick, powerful lugs, exudes an overwhelming presence that remains timeless even in modern attire.
■ "80 Microns" engraving that evokes the era
The case back clearly shows the engraving "14K GOLD FILLED 80 MICRONS." This specification boasts a thickness approximately four times that of typical gold plating at the time (around 20 microns).
During the transitional period when domestic watches were moving towards luxury, this proud engraving of a specific thickness can be said to be "a testament to an era where no expense was spared in craftsmanship" before subsequent simplifications. The excellent condition, with almost no exposure of the base metal on the corners of the lugs, eloquently speaks to its high quality.
■ Special movement "SPECIALLY ADJUSTED"
Inside, it is equipped with a 23-jewel movement featuring beautiful rose gold plating. This particular piece is engraved with "SPECIALLY ADJUSTED," indicating that it underwent rigorous adjustment at the time of shipment. This specification showcases the pride of a high-grade watch, meticulously crafted by Citizen at the time in pursuit of precision.
■ Refined details
The radiant finish dial, which changes its expression with the angle of light, is graced by an elegant cursive "Citizen Super Ace" logo. The combination of bold bar indices and dolphin hands creates a classic yet modern strength. This is a recommended item for those seeking a special timepiece that combines dressy elegance with a refined sense of size.
Condition
This watch has been overhauled.
The strap has been replaced with a high-quality crocodile strap made by Di-MODELL, a long-established German brand, allowing you to enjoy its exquisite texture. The buckle features the "CITIZEN" engraving.
The crystal has no noticeable scratches and the time is clearly visible.
The dial shows some aging (discoloration) and subtle dirt due to its age, but this does not detract from its vintage charm, and it remains in good condition considering its manufacturing year.
As this is an old watch, it is not water-resistant. Do not use it in damp environments (rainy days, when washing your face, or on hot days when you sweat a lot).
As it is a precision instrument, please be careful of drops, strong impacts, and magnetism (smartphones, PCs, etc.).
How to operate
How to pull the crown: Push your fingernail between the case and the crown and lever it out.
Pulling the crown too hard may cause it to come off. Please pull it out gently.
To prevent the crown from bending, remove the watch from your wrist before operating it.
Gentle operation can reduce stress on the crown.
Manual winding: Rotate upwards with the crown in the normal position.
Time setting: Pull the crown and rotate downwards.
