Mike's Clock Clinic's Web page for Selling LeCoultre Atmos Clock Parts

Back to the Main page of Mike's Web site.

If you need service then please see my Atmos service page.

I do NOT sell any "new" Atmos parts; all parts are used or aftermarket. No instructions of any kind are send with any part, therefore it is your responsibility to accurately order and all sales are final with some flexibility at my discretion.
Please realize that I'm not a supply house and make my living overhauling the Atmos and I do this so that people have a way around LeCoultre who does not seem to sell any parts.

For a complete list and prices, please see my pdf file: Internet Atmos Parts Prices.pdf

To make sure that you order the right part, please see: Atmos Parts Schematics

All prices listed here are accurate and up-to-date.

In order to assist you in ordering the correct part, you must first determine the Atmos's caliber and use this link to determine the caliber of your Atmos. Once you have determined the clock's caliber then you'll need to know the correct part number. I have this solved by listing most every part for the three LeCoultre calibers. These are all Web page links. The caliber 540 The caliber 528 & 526 The caliber 519 & Atmos II

All prices listed here are accurate and up-to-date. If you are ordering a Suspension Unit, then please specify the Atmos' caliber because an Atmos II and Caliber # 519 take a longer length screwed end (bottom clamp) and all other calibers take the shorter bottom clamp. You must send in your regulating clamp and bottom clamp that are useable, for the $50.00 discount ($25.00 each piece).. To determine your Atmos' caliber, please see Atmos caliber. Or you can measure the threaded area of the bottom clamp.  The longer thread is approximately 22mm and the shorter thread is approximately 17mm.  Please specify either the caliber or the thread length when ordering. Please be aware that all Pallet Fork & Staff's are not in "just drop in condition".  This means that any fork will require adjustments in order to function properly but I guarantee that the fork is complete and will function properly with some minor adjustments, as per the LeCoultre Atmos repair notes. If you are interested in purchasing any of the above then please contact me at Mike and then I'll E-mail you with total costs and then issue a Pay Pal invoice or await your check. You can also E-mail for cost and availability of other Atmos parts. I can also refill your old dead bellows for $300.00 plus shipping but realize that option takes about 6 weeks because I send it to another to be refilled.

For any shipment, it makes the package a little more deliverable if you include a contact phone number. Please include your phone # with your E-mail.

The shipping charge is $20.00 to the US, $45.00 to Canada which includes insurance. This assumes that the shipping weight is under 1 pound, which it is normally.
For shipping to the rest of the world, there are two options to choose.
For shipping outside the US you must choose a value that you want me to place on whatever you order.  This will be the same as the insurance I place on the package because the USPS will not insure an item for more that its value.
This value is very important because you will have to pay whatever import tax your country requires, aka duty fee.  The only way I know to prevent paying duty or customs fees is to not insure the package and taking that chance is up to you.
    1.) First is USPS Priority Mail, using a box of about any size and this includes insurance, with no maximum.  The cost is $65.00.  The package can be tracked and takes about 2 to 2 1/2 weeks.
    2.) Second and last is the USPS Express Mail, using an Express Mail box and this includes insurance, with no maximum.  The cost is $80.00.  The package can be tracked and takes about one week.

Please remember that the insurance amount is also the customs value for country's taxes and import fees.

Free shipping on any order $1,000.00 or more using the Express Mail, option # 2, to anywhere.

I use USPS for all shipping. If you want to use another carrier then you will have to arrange everything for shipping, meaning I hand the box to the driver, get a receipt and nothing else.

For service on your Atmos clock, please see: My Atmos service web page

I would like payment by money order, certified check, personal check, business check, or through Pay Pal or Square, which is the only way I take credit cards. I do prefer a check because Pay Pal and Square take 3%. I only take credit cards if you are in the USA or Canada. The 3% is added to the total bill if you use a credit card or Pay Pal. With Pay Pal you can pay me directly using "friends and family" where you absorb all fees and I'm paid the full amount. There would be nothing added amount to the final fill if you absorb all fees. Here you log on to Pay Pal and send me the full amount of my bill, so there is no E-voice coming from me with this method and you will be charged all Pay Pal fees on top of my final bill. With either Pay Pal or Square, I will send an invoice to your E-mail address. Here you are dealing directly with either service and not me. You do have to be a member of Pay Pal in order to issue a payment but you may use Square without any membership or additional Square fees but the 3% will be added to your total bill as with Pay Pal. With Square, I can also take the credit card information which includes the number, expiration date and the last 3 or 4 #'s of the security code from the back of the card BUT that adds 3.5% to the final bill. I'd prefer to avoid this method but it is an option. All sales outside North America will be charged 4% on top of the total through Pay Pal only. All of the added fees are exactly what either service charges me for taking your credit card.

I have parts for the Atmos II and Caliber 519 (Schematics Link) and these have long since been discontinued, so please be aware that they are very expensive.
Please feel free to contact me at Mike for any Atmos part. If I don't have it, I'll give you another contact who may.
