Vintage Seiko women's watches
The main families in one table, with example movements and the case codes that tell solid gold from plated.
Quick answer
Seiko’s vintage women’s watches fall into a few families: Queen Seiko from 1962, Credor from 1974, Lassale from 1980, Exceline by 1980, and the asymmetrical Rivoli of 1986, now called the Half Moon, plus everyday automatics like the 2205 and 4206. What one is worth depends on the family, the movement and whether the case is solid gold or plated, and the case back code tells you which.
The families at a glance
| Family | From | Example movements | Case and metal | Sold range |
|---|---|---|---|---|
| Queen Seiko | 1962 | Hand-wound mechanical, such as the 1020C | Crown motif on the case back; a platinum example is documented | Sampling |
| Credor | 1974 | Mechanical 6810 and quartz in early Credor catalogs | Started as Seiko’s precious-metal line | Sampling |
| Lassale | 1980 | Quartz, such as the 2F50A | Slim dress cases | Sampling |
| Exceline | by 1980 | Quartz 1400 and 2320 | Oval and rounded-square cases; some 14K gold | Sampling |
| Rivoli (Half Moon) | 1986 | Quartz, such as the 1N00 | Asymmetrical | Sampling |
| Everyday automatics | 2205 by 1970 | 2205 and 4206 | Round steel and gold-tone cases | Sampling |
Queen Seiko
Seiko created the Queen Seiko in 1962 as the women’s counterpart to the King Seiko, according to Seiko Design. The first models were hand-wound, with a box-shaped acrylic crystal, long trapezoid markers and a large crown; later ones moved to a cut-glass style. The case back carries a crown motif. The Watch Bloke’s repair of one, with a hand-wound 23-jewel 1020C, was platinum, so don’t assume every Queen Seiko is steel or plated.
Credor
Credor began in 1974 as Seiko’s high-end line in precious metals and took its crest logo in 1980, according to Credor. Plus9Time notes that early Credor dials can still read Seiko, with Credor appearing only in the catalog, so a dial without the Credor name isn’t necessarily wrong. Early Credor catalogs show both mechanical models on the 6810 and quartz models, though we haven’t confirmed which of them were women’s watches.
Lassale and Exceline
Seiko’s own timeline puts the Lassale in 1980, popular abroad first and then sold in Japan. Seiko’s parts catalogue for the 2F50A quartz movement carries the Lassale name, though other Lassale movements exist. The Exceline appears in Seiko’s 1980 Japanese catalog with 1400 and 2320 quartz movements in oval and rounded-square cases, some marked 14KYS.
The Half Moon
The watches people now call the Half Moon trace back to the Rivoli, which Seiko dates to 1986: an asymmetrical design that was especially popular in Europe. GQ notes the nickname came later and isn’t Seiko’s. One dealer’s example uses the 1N00 quartz movement in a base-metal case, so treat gold claims with care.
Everyday automatics: the 2205 and the 4206
Many vintage women’s Seikos are plain automatics, and they’re mechanical, not quartz.
- 2205: automatic with hand-winding, a date with quickset, 28,800 vibrations per hour, 17 jewels in Seiko’s guide. The 2205-0240 is one example; one watchmaker dated his to December 1970.
- 4206: automatic with hand-winding, a day and date with quickset, 21,600 vibrations per hour, 17 jewels in Seiko’s guide for the 4206B. The 4206-0510 is a women’s Seiko 5.
The 1104 is mechanical too, but hand-wound rather than automatic. A seller who calls any of these a quartz watch that needs a battery has the movement wrong.
Is it gold? Reading the case back
The case back often says what the case is made of, though not always. Plus9Time lists Seiko’s material codes next to what’s usually stamped on the back:
- SGP (Seiko Gold Colour Plate) is gold-colored plating; the back usually reads BASE METAL ST.STEEL BACK. SGP30 is 30-micron plating, stamped SGP30 ST.STEEL BACK.
- GF and AGF mean gold filled, stamped GOLD FILLED ST.STEEL BACK or AGF. Not solid gold.
- 18K or K18 is an 18-karat yellow gold case. K18 is the older marking and usually sits inside a square box.
- 14KYS is a 14-karat gold case with a steel back, stamped 14K ST.STEEL BACK.
- SS18K combines steel and 18-karat gold, stamped ST.STEEL + 18KT ST.STEEL BACK. A back that reads ST.STEEL 18KT BEZEL means only the bezel is gold.
A missing stamp doesn’t settle it either way. Go by what’s stamped on the case and the back, not by the color or the family name.
Dating and pricing your watch
The serial decoder reads the month and the year’s last digit from the case back. It narrows the decade only for calibers whose production years we’ve verified, and that doesn’t yet include the women’s calibers on this page, so check the dial style and case too. Our price guide will show sampled ranges for the women’s references after our first sampling.

FAQ
Are old ladies Seiko watches worth anything?
Most are worth something, and some are worth a good deal: a solid gold Credor or Queen Seiko is a different proposition from a gold-plated everyday quartz. Read the case back code first, then the movement.
How much is a women's vintage Seiko worth?
It depends on the family, the movement and the case metal. Our sampled ranges for the women's references appear on this page and in the price guide after our first sampling in November 2026.
Is my vintage Seiko gold?
Check the case back. 18K, K18 or 14K means a gold case, though the back itself may be steel. BASE METAL or SGP means gold-colored plating, and GOLD FILLED or AGF means gold filled, which isn't solid gold. Not every case is stamped, and a gold color alone tells you nothing.
How do I find out what year my ladies Seiko was made?
Use the serial on the case back: the first digit is the last digit of the year and the second character is the month. Our serial decoder reads both. It can only narrow the decade for movements whose production years we've verified, which doesn't yet include the women's calibers here, so use the dial style and case as well.
