Vintage Bulova Watch Value: Date Codes, Accutron and Prices

Most vintage Bulova watches are gold filled or gold plated dress watches worth approximately $20-100, a little more if they run and still have a nice dial. The ones worth real money are the Accutron tuning fork models from 1960 to the late 1970s, especially the Spaceview with its open dial, sport models such as the Oceanographer and Snorkel, early collectible pieces like the Lone Eagle, and any Bulova in a solid 14K or 18K gold case, which is worth at least its gold. A Bulova can be dated to the year with the code stamped on the caseback and often on the movement: from 1950 a letter for the decade and a digit for the year, so M7 means 1967 and N4 means 1974.

Quick answer

• Gold filled dress Bulovas: about $20-100. Solid gold cases: the gold value and up.
• Accutron tuning fork watches: $100-600 for most, $400-1,500 or more for good Spaceviews and Astronauts.
• The caseback code dates it: L for the 1950s, M for the 1960s, N for the 1970s, plus the year digit.

How to check yours, step by step

1. Read the dial. Look for BULOVA and, below it, ACCUTRON, AUTOMATIC, a jewel count such as 23 JEWELS, or a model name like Oceanographer, Snorkel or Sea King. A dial that reads ACCUTRON, with a small tuning fork logo, is the first thing to separate.
2. Listen to it. A running Accutron does not tick. Held close to the ear it gives a steady, high hum, and the seconds hand sweeps smoothly. That hum is the 360 Hz tuning fork.
3. Read the caseback. You are looking for three things: the material stamp (10K GOLD FILLED, 10K RGP, ROLLED GOLD PLATE, STAINLESS STEEL BACK, or 14K and 18K for solid gold), a model or case number, and the date code, usually a short letter and digit such as M7 or N4, sometimes with a small symbol.
4. Look inside if the back is opened. A watchmaker opening the case will find the movement calibre and often a second date code on the movement plate. Accutron movements are numbered 214, 218, 2181, 2182, 2185 and so on. Case and movement codes may differ by a year, since cases were made ahead of time.
5. Check for gold. On solid gold Bulovas the karat stamp sits inside the caseback or on the case. If you only find 10K GOLD FILLED or RGP, the gold is a thin layer bonded to base metal and has almost no metal value.
6. Check whether it runs. Wind a mechanical one gently by the crown, ten turns or so. An Accutron needs a battery of the right type. Note whether the hands move and whether it keeps time over a few hours.
7. Compare with sold listings for the same model and case material, separating running and non-running examples.

Bulova date codes

Bulova stamped date codes on most watches from the 1920s on. The older system used symbols, and from 1950 it switched to a letter for the decade and a digit for the year. Codes are approximate in the sense that a case could be stamped in one year and sold the next.

On many watches the date code sits on the caseback next to the case number. On Accutrons it often appears both on the caseback and on the movement, and the two are usually within a year of each other. A watch with an N-code caseback and an Accutron movement from the 1960s may have had its movement replaced, which is common and not a problem on an everyday piece but worth knowing on a collectible one.

Why the Accutron matters

Bulova launched the Accutron in 1960. Instead of a balance wheel it used a tiny tuning fork driven by a battery and two coils, vibrating at 360 times a second, and it was accurate to about a minute a month, far better than mechanical watches of the time. Accutron timers went into the space program, and the watch was a status object for a decade, until quartz overtook it in the 1970s. Tuning fork production ended in the late 1970s.

That history is why collectors pay for Accutrons while ordinary Bulova dress watches sell cheaply. The 214 calibre, from 1960 to the mid 1960s, has the crown on the back of the case. The 218 that followed has the crown at 4 o'clock and came in date versions as the 2181 and 2182. The Spaceview shows the movement through a transparent dial; the first ones were meant as display pieces for jewelers, and the public asked to buy them. Later Accutrons with conventional dials are more common and cheaper.

One caution: Bulova reused the Accutron name for modern quartz watches from the 1980s onward, and in recent years it has sold new Spaceview-style pieces. A modern Accutron is a different watch from a 1960s tuning fork one.

Repair is the other point. An Accutron that does not hum may need a cleaning, a new battery adapter or, worst case, a new coil, and few watchmakers still work on them. Expect roughly $150-400 for a proper service from a specialist, more if a coil needs replacing.

What vintage Bulovas are worth

These are typical approximate prices for running watches in good condition. Non-running ones usually sell for 30 to 60 percent less, or for parts.

The gold value of a solid case depends on its weight and on the gold price on the day. Small ladies' cases hold only a few grams of 14K gold; heavier men's cases hold several times that. A jeweler can weigh the case and give a scrap figure, which is the floor even if the movement is dead.

The honest view on most dress Bulovas

Bulova made millions of watches. From the 1930s to the 1970s it was one of the largest watch brands in the United States, and its gold filled dress watches were standard retirement and graduation gifts, often engraved on the back. That makes them pleasant, well made and common.

Engravings rarely add value to a buyer outside the family, and they can lower it slightly. A small manual wind dress watch with a faded dial and worn plating usually brings $20-50. A clean one with a crisp dial, original crown and the original box can bring $60-150 to the right buyer. Collector interest goes almost entirely to the Accutron line, the sport models and unusual early pieces.

If the watch is part of a wider estate, how much is my watch worth explains the brand tier method, and Bulova pocket watches are covered in old pocket watch value.

Gold filled versus solid gold

This is the single most common confusion with Bulovas.

• 10K Gold Filled, 10K RGP, Rolled Gold Plate: a layer of gold bonded to a brass base. It looks like gold and wears through at the edges after decades, showing yellow brass underneath. Scrap value is close to nothing.
• Gold plated or Gold Electroplate: a thinner layer. No scrap value.
• 14K, 18K, 585, 750: solid gold. The stamp is usually inside the caseback or on the case itself. Many solid gold Bulovas have a steel back, so the case front is gold and the back is not; read both.
• Stainless steel back: a plated or gold filled case front on a steel caseback. Common on 1950s and 1960s dress watches.

A watch marked only 14K on the dial or the bracelet does not mean the case is solid gold. Look for the stamp on the case. The method is the same as for any jewelry, laid out in is my old jewelry real gold.

Common mistakes

• Assuming every old Bulova is collectible. Most dress pieces are worth $20-100.
• Reading 10K Gold Filled as solid gold. It means a thin layer of gold over base metal.
• Mixing up a 1960s tuning fork Accutron with a modern quartz Accutron. The movement and the hum decide it.
• Forcing an Accutron to run with the wrong battery. Old Accutrons need the right battery or an adapter.
• Ignoring the date code. Two watches that look alike can be a decade apart, and the Accutron era matters.
• Opening the caseback with a knife. Scratches and dents cut into what little margin a dress watch has.
• Valuing an engraved watch higher because of the engraving. Buyers outside the family usually pay less.

What to photograph

• The dial straight on, without glare, so every word is readable.
• The caseback, flat and sharp, showing the material stamp, case number and date code.
• The inside of the caseback and the movement, if a watchmaker has opened it.
• The crown position, which separates a 214 Accutron (crown on the back) from later models.
• The case edges and lugs, where worn gold filled plating shows brass.
• Any box, papers or receipt.

When to get it looked at in person

A local watchmaker can open the case, read the movement and its date code, and say whether a mechanical Bulova needs a service, often for roughly $25-75 for an inspection. Service on a vintage manual wind Bulova usually costs roughly $100-250, which is more than many dress Bulovas are worth, so it only pays for a watch someone wants to wear or for the better models. For an Accutron, look for a watchmaker who specifically services tuning fork movements; a general shop may decline it.

For a solid gold Bulova, a jeweler can test and weigh the case. That sets the floor, and it is worth knowing before accepting any offer.
