The Rolex caliber 3000 automatic watch movement was introduced in 1990. It was used until around 2001. Found in Non-date models: 14000, 14010, 14060, 14270.
Walt Odets did a review of the Rolex Explorer 14270 on Timezone. Some notable points about the caliber 3000:
Although the movement is largely conventional in design, there are a few unusual design features. The bidirectional automatic winding system is similar to the ETA/Eterna system in using a pair of double-click wheels for winding reverse. The two “red” wheels appear to be fabricated of a light alloy, and are coated with PTFE (“Teflon”) for lubrication of the outer teeth and inner clicks… The automatic winding system is the single best-finished part of the movement…The simplicity and over-sized design of the automatic winding system characterizes the entire caliber 3000… The only other unusual design feature of the caliber 3000 is the use of a flat (i.e. without overcoil) hairspring without a regulator and an extremely simple version of an adjustable-mass balance…
From padi56 in the Rolex Forum:
The main difference with the 3000 and the 3130 is its got a full balance bridge, larger balance wheel breguet overcoil basically its now a cal 3135 without the date complication. But the cal 3000 was fitted in the Explorer now that was COSC tested but the non date sub was not, exactly the same movement in every way. Both movements are excellent in accuracy and longevity of life and very little between them myself like the 3000.
The 3000 is essentially the same movement used today but was the last of the Rolex in-house movements upgraded with the, before mentioned, full bridge, larger balance wheel and breguet overcoil to become the 3130…
