Edma Chronograph Cal. 7733, 1972

Orange chronograph accents animate the silver-and-black panda dial of Edma Chronograph Cal. 7733 from 1972. The men's Swiss hand-wound watch has running seconds at 9, chronograph minutes at 3 and a black outer tachymeter scale, with applied baton markers and 17 Jewels lettering. A broad polished steel cushion case, right-side crown and pushers, and perforated rally-style leather strap carry its sporty character.

Panda dial and two timing registers

The main dial is light silver, contrasting with two black subdials. Running seconds occupy the register at 9 o'clock, while chronograph minutes appear at 3. This bicompax arrangement keeps the time and elapsed-time indications balanced across the face.

A black outer tachymeter scale frames the display. The orange central chronograph seconds hand stands clearly against the silver-and-black background, with matching orange details inside the chronograph register. These accents give the watch its documented motorsport-inspired appearance without implying competition provenance.

Applied batons and Edma lettering

Edma is signed below 12 o'clock, and 17 Jewels is printed above 6. Applied baton markers have dark central inserts and match the slim central hour and minute hands. The contrast between the dial surface, black registers, dark inserts and orange timing details makes the individual layout clear.

The panda arrangement and vivid chronograph accents express the sports-watch design of early-1970s vintage watches. Its markings and register positions retain the individual timing layout.

Cushion case and condition

The broad stainless steel case has a cushion-style shape, polished surfaces and rounded edges. It gives the watch greater presence than traditional round dress chronographs. The crown and chronograph pushers sit on the right side, with a raised crystal above the dial.

Visible signs of age and use remain on the case. The caseback also shows normal use and handling marks. Those marks accompany the polished finish and used vintage condition.

Valjoux 7733 hand-wound mechanism

The Valjoux 7733 is the manually wound mechanical chronograph movement inside the watch. Its construction includes visible levers, bridges and jewels, with traditional hand-wound operation. The 17-jewel specification agrees with the dial inscription.

The robust, practical movement design fits the two-register timing arrangement. Manual winding supplies the regular ownership routine, while the running-seconds and chronograph indications remain distinct.

Perforated rally strap and service

A rally-style leather strap with large perforations reinforces the sporty presentation. Its design suits the tachymeter scale and orange timing hand, supporting casual wear or a mechanical-chronograph rotation. Strap color and replacement status are unspecified.

This used Edma is fully serviced and comes with a 12-month warranty. Its panda face, orange accents, cushion-case geometry and Valjoux 7733 mechanism remain the defining features of this 1972 chronograph.
