OMEGA Seamaster Ref.2576-5 Tropical Dial Bumper

COMMENT

シーマスター 1st ジェネレーションのスモールセコンドモデル、Ref.2576です。年式ごとにケース形状やムーブメントに細かな変化が見られますが、この1.35mil -5はその中でも最後期のモデルにあたり、横穴のない太いラグが特徴的です。ブラックギョシェダイヤルには力強いアプライドのクサビインデックスが配され、幅広のドーフィンハンドが組み合わされています。

ムーブメントには1940年代から1950年代にかけて製造されたオメガの自動巻きCal.344を搭載。全回転式ムーブメントが登場する以前の主流であった半回転（ハーフローター）式、通称「バンパー」を採用しています。手巻きから自動巻きへと移行する時代を象徴する機構で、腕に振動が伝わる独特の感触が魅力です。ヴィンテージ機械式時計ならではの味わいを堪能できる一本です。

ケースは小傷が少なく清潔感のあるコンディションで、特に傷がつきやすいラグは美しい状態を維持しており、好印象を与えます。ダイヤルはエイジングによりトロピカルと呼ばれるブラウンチェンジを見せており、全体に均一で、ミントコンディションと並ぶ評価の高い経年変化を遂げています。針はくすみがなくシャープな輝きを放ち、インデックスは三面ファセットが美しく仕上げられ、光を受けて華やかに輝きます。弊社にて分解清掃済みです。

ヴィンテージウォッチならではの個性が際立つ一本。クラシックな意匠を備えながらも洗練された美しさを持ち、シーマスター 1st ジェネレーションの魅力を存分に味わえるモデルです。ブラックギョシェダイヤルの奥行きある経年変化、バンパー式ムーブメントが生み出す独特の操作感、そしてシンプルながら計算されたデザインが、長年愛され続ける理由を物語っています。実用性を兼ね備えたヴィンテージウォッチとして、コレクションの一本にはもちろん、日常使いにも適した存在感のあるタイムピースです。シーマスターという名を冠するにふさわしい質実剛健な一本を、ぜひご堪能ください。

腕時計が普及し始めた1910年代から手巻き、自動巻と変遷を経て、クオーツ時計の開発によって機械式時計が衰退します。それ以前の1960年代に機械式腕時計はひとつのピークに達します。当時は日本でも三種の神器の一つだったオメガの時計。持つ人のステータスとなる高級品で、各メーカーが精度や防水性、耐久性など切磋琢磨し開発した時代。コストをかけて、より良い時計造りのためにしのぎを削っていました。

The Seamaster 1st Generation Small Seconds model, Ref. 2576, showcases subtle variations in case design and movement across different production years. This particular piece, with a 1.37mil serial, belongs to the final production period and is distinguished by its thick lugs without lug holes. The guilloché dial features bold applied wedge indices combined with Arabic numerals at 12 o’clock, complemented by broad dauphine hands.

Powering this model is the Omega Cal. 344, an automatic movement produced from the 1940s to the 1950s. It utilizes a bumper winding system—a half-rotor mechanism that predates the full-rotor automatic movements. This transitional technology offers a unique tactile feedback, allowing the wearer to experience the distinct vibration of the oscillating weight. It is a timepiece that embodies the charm of vintage mechanical watches.

The case remains in a well-preserved state, exhibiting minimal wear and maintaining its sharp, clean lines. The lugs, often prone to scratches, retain their original form, adding to the watch’s overall appeal. The dial has aged gracefully, developing a warm, refined patina, while the hands remain free of tarnish, exuding a crisp brilliance. The tri-faceted indices retain their sharp edges, catching light beautifully. This watch has been professionally serviced by our team.

This is a timepiece that exemplifies the character of vintage watches. The guilloché dial, wedge indices, and small seconds subdial positioned to balance the Arabic numeral at 12 create a harmonious design. While maintaining a classic aesthetic, the Seamaster 1st Generation also exudes an understated elegance, making it a remarkable piece to appreciate.

The Seamaster 1st Generation small seconds model, Ref. 2576. While subtle variations in case design and movement exist across different production years, this particular example, with a 1.35mil -5 serial, represents one of the final iterations, characterized by its thick lugs without lateral holes. The black guilloché dial is adorned with bold applied wedge indices, complemented by broad dauphine hands.

Powering this watch is the Omega Cal. 344, an automatic movement produced between the 1940s and 1950s. It features a half-rotor "bumper" winding system, a hallmark of the transitional period from manual to automatic movements. The distinctive tactile feedback of the bumper rotor, transmitting a subtle vibration to the wrist, is a defining characteristic of early self-winding watches, offering a uniquely vintage mechanical experience.

The case is in excellent condition, with minimal surface marks and a well-preserved, crisp appearance. The lugs, particularly susceptible to wear, remain in beautiful shape, contributing to the overall strong impression of the piece. The dial has undergone an even tropical transformation, shifting to a deep brown tone that rivals mint-condition examples in desirability. The hands retain a sharp brilliance, free from tarnish, while the three-faceted indices catch the light exquisitely, enhancing the dial’s rich depth. Fully serviced by our team.

A timepiece that exemplifies the character of vintage watches.

The black guilloché dial, enhanced by its remarkable aging, the unique feel of the bumper movement, and the well-balanced, purposeful design all contribute to its enduring appeal. Combining vintage charm with everyday practicality, this is an exceptional piece for any collection or daily wear. A robust and uncompromising Seamaster that truly lives up to its name—one to be experienced firsthand.

From the early 1910s, as wristwatches gained popularity, watchmaking evolved through hand-wound and automatic movements before the quartz revolution led to a decline in mechanical timepieces. However, by the 1960s, mechanical watches had reached a pinnacle, with Omega standing among the most prestigious brands—so much so that its watches were regarded as one of Japan's "three sacred treasures." It was an era when precision, water resistance, and durability were fiercely pursued, with manufacturers sparing no effort or cost in their quest to build the finest timepieces. These qualities, now found only in vintage models, remain a testament to the craftsmanship of a bygone era.
